A sexual term, it is when you take your significant other, and pin them against the wall. While they are pinned against the wall, you spread their legs and insert your penis into their anal cavity. While giving them anal, you then take your thumb, and massage the clit. While massaging the clit, you take your middle and index finger and make a come hither motion in their love hole. Make sure you pull their hair back for the full effect.
Yo, last night, I gave my girlfriend "The Old Sandusky".
High five bro!
