To be so hypnotized by (or obsessed with) a guy's dick that a girl/guy will let them do crazy things and they think nothing is wrong with it
Jill got so dickmitized by that unemployed guy who smokes pot and sleeps on the beach that she let him borrow her car for a month and he drove it into the ocean.
Someone that is a complete dick on Twitter. This person will follow large quantities of people in order to build up their follower count, only to unfollow those people at a later time once being followed back. Therefore having a follower to follow ratio of 10:1. It gives the appearance of being more popular than they actually are. Hipster douchebags are usually the ones that practice this dick move.
