2) and by whom every other man will be stereotyped henceforth by these very girls.

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

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."
