The Cummings Invite meant you where invited over for unprotected sex and would be cumming inside of her pussy.
Theresa just gave us the cummings invite again. Do you guys want to go?
When you find out about a party that you felt you should have been invited to but never heard about it until later... You were cummings invited..
" Yo, "Tim's" bachelor party was the greatest ever! Why didn't you come?"
"I guess I got the cummings invited... Fucking asreholes...."
