Peter's Road Trampoline 

When someone rests their head on the lap of a male, this is usually considered a cute moment up until the point where the male's lightning rod gains a surge of energy resulting in the repetitive up and down of the partners head on their lap. This must be followed by the question: "Is your dick bomb?" in order to prevent bad luck.

*ON BUS*
Person 1: "Dude, my dog was resting his head on my lap the other day and, out of fucking nowhere, I had the worst Peter's Road Trampoline."
Person 2: "Was your dick at least bomb?"
Person 1: "Of course what do you take me for!"

trampoline sponge cow

when you walk in on your fat parents having sex and they both look at you without stopping, smile at you, and then continue to cause creaking that can be heard throughout the whole neighborhood. You are traumatized for life. Your childhood is over because of what you've just seen.

"hey what's up" "don't talk to me. I experienced trampoline sponge cow last night" "oh gosh man I'm so sorry."
