trihole

The three orifices in a woman that can generally accept a penis.

Mark, Bill and I triholed Debby last night. Afterwards Mark and Bill double felched her, but I've got standards.

Bermuda trihole

The appearance of a lady's nether regions following intercourse with three simultaneous cocks.

I was going to fuck her, then I saw she had a Bermuda trihole and I was like "I'm outta here"
