Sweaty Santa
Verb: When a couple is passionately 69'ing and the male is about to ejaculate, the duo flips over such that the male is on top. Immediately after flipping, the male shoves his erect penis deep inside the female's throat and deposits a massive amount of ejaculate; like Santa "cumming" down the chimney and leaving a "gift."
"I was 69'ing with the wife by the fire last night and I gave her the ole Sweaty Santa. Merry Christmas!"
