Short for
kickee pants which is a type of sex girdle commonly used among
post partum women to keep breasts lifted, FUPA minimized, and vaginal lips closed. A pair of unicorn kickee pants commonly has an extra hole area for strapping on/in
adult toys.
If I'm ever going to use all of these baby things I've been
hoarding, I better put on my
kickee pants so my husband will do
the deed with me.
