The sound of a large cock falling out of your pantaloons
Her eyes widened when she heard the fwump of my cock after unzipping my pants.

My step-mommy couldn't believe her ears when I took off my towel and my cock fwumped out.

The sound a forceful poo deposit causes when it makes contact with the water in a toilet.
I squatted down and then fwump! my ass was soaked after a tsunamic reverse flush.

when you attempt a fist bump, but your friend does a high five ending up in a half fist bump, half high five.
