Scrim- The complete and full process of trying to engage in conversation with a female to acquire her number. Scrim is also used in the context of trying to "holler" at a girl before dating officially. For instance like unofficially going to holler at a female.
The scrimmage "scrim" is what happens before the real game (dating) actually starts.
once you receive the girls number "scrims" go from unofficial to official. After official scrims and the actual relationship status changes you are no longer "scrimming."
"Do you want to go scrim?" which mean do you want to go holler at some girls.
"Lets go to the mall and scrim some baddies." which means going to holler at sexy girls at the mall
