Another definition for the word that people use for mean idiots.

Verb - To perform the dance style known as jerking, which involves such moves as the Stanky Leg, the Dip, and the Reject. This trend grew due to songs such as 'Teach Me How To Jerk' by The Pu$h and 'Your a Jerk' by New Boys.

Noun - One who performs this dance. Jerks typically have a high degree of swagger in their demeanor.
1) "Yo, can you teach me how to jerk?"

2) "Hey, check that kid's fresh Reject."
"Yeah, what a jerk."

A not so nice man:

1) for whom most girls would fall for, only to get used throughly and dumped quickly...
2) and by whom every other man will be stereotyped henceforth by these very girls.
Don't bother...he looks too nice to be a jerk!
