An onslaught of dong, or lots of dong being used in offensive measures to humiliate, irritate, or copulate. Usually associated with Omegle Video, Chatroulette, and band trips.
Naive little Charlie was corrupted by a dongslaught on Omegle Videochat.
After having sex with the pinnacle of vagina, you pull your duck out, scream DONGSLAUGHTER, and cut your penis off. Because you cannot fuck anything better.
Yo!! I just fucked Zach Wilson’s mom!!! I yelled Dongslaughter and cut my Dick off as I’ve reached the pinnacle.
Buddy, congrats man!!!
