ka-thunk

Onomatopoeia of a headboard repeatedly striking a wall, ostensibly due to people fucking in the bed that holds said headboard.

I couldn't sleep last night because Jared and his girlfriend in the apartment next to mine were fucking for most of the night. All I heard was "ka-thunk, ka-thunk, ka-thunk", punctuated by an occasional moan or loud request for one party to fuck the other one harder. I let the air out of that faggot's tires for that.

thdunk

To slap another person across the face with your penis. So named because of the sound it makes upon doing so.

Chrony heartily took Tamara's suggestion to thdunk her.

Thunk

1) A question that makes you think about something you've never thought about before and that then makes your brain ache when you try

2) The noise your brain makes when it starts to think about such questions

Is a broken down car parked? Can you touch the wind? If we swapped brains which one of us - if either - would be me? These are all great Thunks.
