When you give a girl laxatives. Then proceed to perform anal on her. After a while surprise her and pull out real quick and jump on her back yelling Yahoo! Yahoo! like Mario. She then shits everywhere from the surprise.
"I gave my girl "The Yoshi" last night. She loved it"
"This random guy did "The Yoshi" to me yesterday. I came everywhere."
"I did "The Yoshi" to my homie. He hasn't talked to me ever sense."
