When a guys pants are hiked up severely in the front, so badly that it presses his nuts out to each side, therefore creating the look of a chipmunk with it's cheeks full.

Fatty with high-pitched voice who frequently gets beat up badly by younger girls, likes to pretend hes smart and rub it in your face, babied by his mom and treated like a 3-year-old.
Tattle-tale who tells his mommy when ever someone is doing something "bad" and has his mommy pick him up. Weak loser with no friends.

'Chipmunk' - Most girls you see with a decent looking guy, although they may be attractive they look very chipmunk/ferrit like. Not only this but these girls tend to be very fake.....and usually end up being psycho stalking ex girlfriends.
''My friend 'the sleaze' is really into this guy DM, but his Chipmunk is on the scene'' ...... ''Wait, isn't that the Chipmunk who started a fight in that club last weekend?'' .......''Yeah....psycho Chipmunk!''
