During a gang-bang, multiple men ejaculate into the anus of one woman or man, until their anus becomes full of semen. The semen is then eaten by another individual.
Patty: "I went to my first gang-bang last night."
Christina: "How was it?"
Patty: "It was great! They gave me a Portuguese Cheese Cork, and then another girl ate it."
The proper name for someones non-erect cock that has been placed in someones throat, making said cocks girth increase no larger than the size of a cork. Similar to skinflute. A common occurrence in Canada.
Canadians are always putting their skin corks down my throat and I find it rather bothersome. I don't want a cork of skin in my throat, it is gross.
