Multishirting

The process of wearing more than one shirt, giving each shirt a specific task.

I usually wear three shirts. If I take the top one off there is a chance I'm going back out. If I take the middle one off, I am not leaving for sure. If I take the final one off I am going to bed. Multishirting is the best.

Random guy: Hey, what are you guys all laughing about?

(gets a message)
Chatting guy: LOL, he totally does!
