any woman who heads to a party as an anonymous onlooker, drinks five or more cups of jungle juice, and possibly walks back to a boy's room with him; may or may not want sex regardless of said actions
"I got to bang Melissa last night after her 5th cup of jungle juice."
"Dude high five! She's such a kneppie."

"Hey man, it's 9:30 on a Friday night. Time to go sit outside and watch the kneppies gather for frat parties."

"Some hot kneppie came back to my room last night. I wanted to do her, but I was afraid to because she was so incoherent and unable to give consent and it might have been considered rape."
