Created when a woman is on her knees and forearms sticking her ass in the air thus making a 'stump' ready for pumping by her male partner.
"Dude, last night was awesome. We went back to her place and the next thing I know, she takes off her clothes and makes a pump stump right in the middle of the living room floor. Rug burns on my knees are killing me."
