If there is not enough room in the car, a bitch who is unattractive sits in the trunk. Even if there is room in the car for her to sit, you still have the option of putting her in the trunk. This term could also be used to describe someone who is ugly.
*Example 1*
car driver: oh theres not enough room, one of you has to sit on a lap
trunk bitch: ill sit on a lap
me: nah, youz a trunk bitch get in the back!
*Example 2*
friend: DAMN that girl is ugly!
me: yeah, she a trunk bitch
car driver: oh theres not enough room, one of you has to sit on a lap
trunk bitch: ill sit on a lap
me: nah, youz a trunk bitch get in the back!
*Example 2*
friend: DAMN that girl is ugly!
me: yeah, she a trunk bitch

When you are fed-up with your bitch/ho not giving you the green you place her swiftly into the trunk of a motor vehicle and slam your fist into the trunk while shouting at her: "Where ma money, bitch?" Where ma money !? Where ma muthafuckin money ho?"
"The pimp was getting tired of his ho dodging him so he trunked the bitch."
"Niall was being nagged by his woman half-bitch. Then he trunked her. Problem solved."
"Sometimes ya just gotta trunk a bitch." - a pimp to the district attorney
