look up any word, like yeet:
 
1.
To refrain from usual habits of slacking on school work to boost up one's grade
" Yo, i'ma geek up this week to pass my driver's ed test"

2.
To step up and do something as a geek. If you're asked to help a relative configure their home computer, or if you're asked to volunteer your geek skills for a worthy cause, you're being asked to "geek up."
We really need your help for this charity event. Just geek up and help us!
