When your dick has had too much to drink. When your dick is singing 99 bottles of beer on the wall, acappella style and it only has 4 bottles left. When the tip of your dick has self esteem issues and bury its face like an ostrich. When your ill na-na is like hello and his peen is working on its fourth nap. When his dick is at half staff... and half stiff. When a safe uber ride home couldn't sober that schlong.
Your best friend, your number one ace who always has your back no matter what. And when his girlfriend questions the box of empty condoms in the glove compartment, he will jump in and take legal ownership of your infidelities.
