When during a threesome, he or she takes a mouthful of cum, and then forces it into the third parties asshole via their mouth.
Dude, my girlfriend totally tossed the sauce with our pick up last night!
When you're hitting it from the back so hard it sounds like you're chopping wood.
Guy one: "Man what the fuck! Was some asshole chopping down a tree in our yard last night?"
Guy two: "No bro, that was me hitting my girl from the back son. That's what it sounds like when you chop that seat."
When you cum in your partners asshole, and then eat out their ass.
Guy one: "What did you and your girl do last night?"
Guy two: "We got freaky homie. I went to toss the sauce and everything!"
Guy one: "That's fucking nasty bro!"
