Dockworker is a slang term derived from MMORPG's, and originates from the phenomenon of Men playing Female Characters and then pretending to be women outside of the game.
Often used as a more derogative form of G.I.R.L (Guy in real life.)
Dockworkers can often be identified by an over use of pink, making everything into a sexual advance and adding *Giggles* at the beginning of most sentences.
Timmy: So I met this chick online and we started hitting it off, she was all chatty and flirty and before I knew it, we were cybering.
When I finaly convinced her to talk to me on Vent I found out she was a DUDE!
Tommy: Hey man, dockworkers need love too!
