Back Bumper Bust

When you fuck a girl in the open space of your trunk and after you finish, you push her down in the trunk space, slam it shut and drive her home while she's in the trunk.

I gave bridgette a back bumper bust last night, she was so mad.

bumpermagnet

A stupid bicycle rider/skateboarder who does not follow rules or, especially, common sense when riding on streets with cars. Mostly seen in college towns or larger urban settings. This can also pertain to walkers, stroller pushers, joggers and fitness fanatics who "can't let my heart rate drop". Unfortunately, sometimes it drops to ZERO bpm.

ASU has a large number of bumpermagnets on the street. Especially between 8AM and 3PM.

The best way to become a bumpermagnet is to wear headphones while skateboarding in traffic. Lucky is when you just get a case of road rash.

This bumpermagnet was nothing but a smear on the pavement when he ran a stop sign when a bus was coming.
