Mexican Frootloop
A Mexican Frootloop refers to a man's scrotom whilst he is in the act of pulling his testicles up, over his erect penis. One testicle is pulled up on the left side, and one on the right so that they meet in the middle above the penis forming the scrotom into a loop.
I woke up in the morning, and walked to the kitchen to eat breakfast with my girlfriend. When I arived at the kitchen she asked me if I had any cereal. To which I replied... "I'll give ya some cereal BITCH!" As I ripped off my pants and gave her the ol' Mexican Frootloop.
