When a girl's pubic region is between groomings (i.e. shaving/waxing) and the hair begins to grow back, it is typically short, coarse and prickly, like a cactus.
During that phase, she can be said to have a "cactapuss", also can be referred to as a 'cactapussy'.
"I need to make a waxing appointment to take care of this cactupuss"
"I can't fool around with Tom tonight, I gots a bad case o' cactapussy"
"Cletus, get your bitch ass over here and water my cactapuss"
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
