A big fat pulsating cock, usually a party of old men with large erections. Similar to a Lemon Party but much dirtier.

Get the dusty cactus mug.
Any hole or object used to have intercourse (or masturbate with) that is very dry. Feels as though your penis is being harassed by a cactus. Often leads to chaffing and inevitable pain with possible blood loss.
That was one hell of a night, but her asshole is a dusty cactus.

She said to stick it in, so I did. We didn't have any lube for that Dusty Cactus. Owey

My cock is so raw that it's bleeding. Damn Dusty Cactus. I'm never doing anal again.
