What is Taco Hat?
1.
Sticking your entire head into a vagina.
"Somewhere, to what remote and fearsome region I know not, my head has gone. I was with her the last night she lived among men, and heard her screams when the thing came to her; but all the peasants and police in County Meath could never find her, or the others, though they searched long and far. And now I shudder when I hear unimaginable and blasphemous sounds, the sounds of...a taco hat."
