: : : : Is anyone familiar with the saying "doing something for blood? "I heard it used like this, "I don't teach anymore for fun, I teach for blood" And they seem to mean it in a possitive way.
: : : : Thanks in advance.
: : : In your example, it would mean something like 'with a vengeance', to use a different idiomatic phrase. It means the teacher has become annoyed with the students not learning, so he/she is going to get serious with them.
: "No more Mr. Nice Guy; this time I'm out for blood."
Sounds like it's derived from the phrase "not for blood or money". This describes a hopeless quest, like "we tried dozens of hotels but we couldn't get a room for blood or money".
Maybe "teaching for blood" is away to avoid admitting that one is teaching for money, now that it's no longer fun!
