Er, it's called slang mate. It doesn't make sense to you because you just went and googled it. You've obviously never used it before.
Anyway OP. I believe there are two types of fobbish girls; goody-two shoed, never-been kissed, nerdy ones and boy-crazy, vain, ditzy ones. Considering your intentions, I guess you're better targeting the latter category. However, get ready to be dropped at a whim. Seriously, they are pretty fickle creatures.
The nerdy ones will never let up until they finish their degree, although it's possible to have a great friendship with them. Just be ready for the mundane, repetitive talk/whine about study. If you really want to pursue it, I guess you could pretend that you're interested in their studies.
