Top Definition
A rubber dildo which is deliberately made porous by means of chemical decomposition, then is soaked in diarrhea.
Me: Hey Brad, your girlfriend's diarrhea is so gnarly that a cleveland bosco stick fell out of her ass when I was fucking her last night.
Brad: How'd she forget about that thrilldo long enough for it to start rotting, anyway?
