Benjamin Buttoning 

When you are about to plug a girl, but you are drunk so your johnson is a little soft. You shove it in anyway, but during the first few minutes your johnson looks wrinkly and old. Eventually, you become fully hard and the shaft is smooth and young-looking.

Andrew: After the party I took a girl upstairs and gave her the business. It took me forever to get hard and I couldn't keep her waiting, so I did a little Benjamin Buttoning in her clap trap.
Evan: Sweet!
