A sexual position between any combination of two people (male/female, male/male, female/female) in which the anus's of each participant are rubbed together. Often used as a last resort for sexual positions, the act can provide immensely pleasurable sensations for those with highly sensitive anal lips. This sexual position is not to be confused with the Spritely Elf.
Ken and Cory finally attempted the Grumpy Troll position after exhausting all other sexual avenues with each other.
The act of two individuals rubbing their buttholes together in a misguided attempt to achieve sexual pleasure. So named for the involuntary noises and facial expressions made by the participants during the act.
Person 1: Guys, I tried the Grumpy Troll last night.
Person 2: Seriously? Feel anything.
Person 1: Nothing. Literally, nothing.
Person 2: How hard did you try.
Person 1: Let me put it this way. I'm much grumpier today.
