Someone who feels that her boyfriend is 'her man' and only her man. Easily gets jealous when other girls are around, even though nothing is going on, they are just friends. Repeatedly accuses boyfriend of being a so-called 'man whore' and thinks of him cheating on her constantly. Always up his butt 24/7 and won't get him out of her sight in fears of him 'whoring around'. Gets mad when he mentions friends, girl or guy, because "nobody can speak to him except her." Always tries to change him, and criticise him.
She doesn't know yet, but he'll eventually dump her controlling ass because she is the one cheating on him, and he'll get with his friends sister, hahahahaha.
Andrew: My friends are taking me to a show tonight.
Jen (Controlling Girlfriend): Are you going with any girls?
Andrew: Yes, a few of them will be there.
Jen: What!? You jiggilo! If you put one foot near that concert it's over! And I mean it this time! No getting back together after three days like always! (will eventually try to get him back anyway)
