Bumpercoat 

1) A winter game in which one person wearing a puffy coat forcibly bumps into another person wearing a puffy coat, triumphantly declaring, "Bumpercoat!" It is similar to bumper cars, but with humans and puffy coats.

2) When you're fucking a girl doggy-style, you pull out and skeet all over her ass, coating it with jizz.

I totally bumpercoated Eliot last night!

Bumpercopter 

The most awesome game ever. You get a helicopter in GTA4 with a star level of at least 3, and then use that helicopter to knock any other helicopter out of the sky.

WOAH! Martin is playing Bumpercopter! Such as awesome game!

bumpergating 

To tailgate someone so that you can read their bumper stickers.

There was this guy in front of me whose bumper was covered with funny ass stickers...I almost hit him because I was bumpergating him.

bumpercasting 

Expressing your point of view through an over abundance of bumper-stickers.

I get you are pro-life, but do you need all the bumpercasting? I can't see what color your car is.
