A vagina that has been unshaven for no more than one week so that the hair growth is stubbly and razor sharp to the touch of a man's penis, thus resembling the spiny cactus leaf. Cacti, like the woman's vagina, can be found in a variety of shapes and sizes.
1.) If she isn't sporting a pink cactus tonight I may just lose my shit.

2.) I told my girlfriend who advocates clean-shaven vaginas that if she does not endorse the use of pink cacti then I will have nothing to do with her ever again.

3.) I love fucking pink cacti. It's nice when it's dark and you're in a hurry.
