Cactapuss 

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"

cactapus 

1. Often used in frustration, the term for that moment when the right word is somehow stuck in a way that it cannot be expressed and therefore results in either hilarity or embarrassment.

2. Refers to the eight-tentacled creature whose suction cups are replaced with painful needles similar to a cactus.

"Dammit! I keep having a cactapus!"
"A what?"
"Like a brainfart except with words."

"Never hug a cactapus. Their tentecles are PAINFUL!"
