Is a sex position where you have three people one male, and two females. The male is on the bottom laying down, while one female is facing towards your feet and giving the male a blow job, as to where the second female is sitting on the male's face while he eats her out and the female giving the blow job lifts her legs over the other female's shoulders and lets her eat her out. Therefore this forms a Triangle.
Triangular Three
1. Having male and two females. The male is laying flat on the bottom.
2. Female number one faces towards male's feet giving him a blow job.
3. Second female sits above male's face and facing the first female's vagina while he eats her out.
4. Second female then lefts up the first female's legs over her shoulder and eats her out.
5. This forms a Triangle leaving everyone receiving oral.

A sexual act where three males insert their penises into one woman's vagina or mouth. As they "cross swords" they shout "ALL FOR ONE AND ONE FOR ALL". Can also be performed orally between 4 gay males.

Three pronged is when you are really, really, really stoned and you feel like your body has turned into three prongs and a tip: the head is the tip, the two arms are each one prong and the two legs morph into one and together make the third prong.
A variation is when you have 4 prongs. That is so your cunt can breathe and is not like tutankhamun's grave in the valley of kings.
