look up any word, like bias:
 
1.
A group of males who successfully pick up women on a consistent basis. They strive to seduce the most beautiful of women, but as the night wears on they tend to lower their standards. If a member of a Grease Team hooks up with an unattractive girl, his "Greasiness" level rises.
"Dude, did you see Taylor last night? He was SOOOO greasy!

I know, man! He hooked up with such a grenade! Grease Team for life!"
