Speed Blump 

Receiving a blumpkin (taking a shit while you're getting some dome) while driving. This can be done either into a bed pan or just onto the seat if you really don't give a shit.

Rebecca gave you a speed blump last night? Was it in a bed pan or did you just let it fly free?

A sexual act in which a man receives oral sex whilst on the toilet suffering from diarrhea.

I ate too much sloppy Mexican food for dinner, but my wife helped me through my pain by giving me a great speedy blumpkin.

Saginaw Speedbump 

A hairstyle made popular in Saginaw, Michigan, in which a woman's hair is pulled up into a full or half ponytail and then pushed forward and sprayed, resulting in a bump of hair on the top of her head that makes her skull look convex.

Kyle: Did you have a nice time in mid-Michigan?
Kristi: How did you know I was there?
Kyle: Honey, the Saginaw Speedbump gives it all away.

San Francisco Speedbump 

When you hit a bump in the road while driving and go flying through the air. Meanwhile, your passenger unknowingly slips a dildo under your ass, spearing you as you land back on your seat.

I hit a giant pothole on the highway, and before I knew it, the gay hitchhiker I picked up had given me the San Francisco Speedbump.

Arizona Speedbump 

You fuck a bitch and then run her over with a car.

I'm glad you had a good time at dinner, how about a Arizona Speedbump for dessert?

That bitch is about to be on the receiving end of an Arizona Speedbump.
