A way of referring to sexual intercourse with two (2) female partners, commonly called a threesome. Famously referenced in the CBS comedy "How I Met Your Mother". The first man in a group of male friends to pull off this feat wins the belt as a reward for his skill with women.
Steve: Dude, where were you last night?
Dan: These two girls were hot for me. We all went back to my place and I rode the tricycle with them. I guess I win the belt!
Steve: Dude, I saw those two chicks checking you out. Which one likes you more?
Dan: They're both into me. It's a tricycle!
While nailing a chick from behind (you'll need to be next to a wall) on her hands and knees, quick swipe her arms out and ram her into the wall!!! And yell out Broken Tricycle!!!
So last night I broken tricycled my wife and sent her head through the drywall:)
Noun: A sexual positon in which the female is in a dog like postion with the male grabbing her arms behind her back
(like handlebars) and pulling back on the arms and thrusting forward with his pelvic region. At this point the women is only supported by her knees and face. Enjoy!!!
