Be there or be square means turn up to the event or be thought dull and out of touch. The phrase is American, and it turns on the slang sense of square, meaning conventional and unfashionable, which Etymonline dates to 1944 in jazz usage. The rhyme is what made it stick.
What is the origin of the phrase ‘be there or be square’?
The common phrase ‘be there or be square’ is American and is generally dated to the jazz scene of the 1950s. Neither Etymonline nor Green’s Dictionary of Slang gives a first printed example of the full rhyme, so that dating rests on the history of the word it hangs on, which can be dated closely.
Before this time, the word square was used to depict anything straightforward and measured, in contrast to the off-beat jamming sessions of jazz music, so in the 1940s, the term ‘square’ was used to refer to someone who failed to appreciate jazz music, and someone who was seen as out of touch with the trend.
Etymonline puts a year on that shift and explains the image behind it: ‘The sense of “old-fashioned” is by 1944 in U.S. jazz slang, said to be from shape of a conductor’s hand gestures in a regular four-beat rhythm.’ A conductor marking four corners in the air is the picture the word carries. Green’s Dictionary of Slang gives the same account for the noun and credits a November 1958 note from the American Dialect Society, which points to ‘the steady 1-2-3-4 rhythm played without variation’.
Green’s takes the insult back further than the jazz decades. It marks the sense ‘conventional, conservative, naive, dull’ as originally African American usage and cites it from 1901, in W. S. Walker’s In the Blood, where a man’s ‘square-clobber’ is his respectable clothing. The older and more flattering senses of the word, honest and properly settled, are the ones that survive in ‘fair and square’.
The earliest example Green’s gives of a square as a person short on cool already rhymes. It comes from the Nashville Tennessean of 27 December 1943: ‘Don’t be a square from Delaware!’ The trick of pairing square with a rhyme was therefore in use before ‘be there or be square’ was, and Etymonline records Squaresville, the mock place name for wherever squares live, from 1951.
The phrase ‘be there or be square’ was popularised by the 1950s. Its sense widened over time, so that the square in ‘be there or be square’ was anyone who did not appreciate the trending counter culture of the day, which is to say anyone who wasn’t cool.
Since its use in the jazz scene, the phrase has come up again and again in other contexts, including in the 1960s disco scene, and later in the 1970s and 1980s the punk rock scene.
The insult has softened, but it has not gone away. The Cambridge Dictionary labels the adjective old-fashioned and informal, and defines it as ‘used to describe a person who is boring and does not like new and exciting things’, which is close to calling someone a stick in the mud.
If you don’t wish to suggest that someone is boring or uncool, it is better to avoid the phrase altogether and to say something like ‘I hope you can make it’ instead.
It works best as a genuine invitation, said when you do expect the person or people to turn up to the event in question.
What are some notable uses of the phrase ‘be there or be square’?
The phrase continues to be used in literature, event promotion, and social media. It also appears in the film Grease, released in 1978 set in the 1950s, and in the American TV series Happy Days, which is also set in the 1950s.
