A man who's penis is extraordinarily small, promting users to feel that his package was comparable to a tiny snack purchased from the dollar menu at a fast food restaurant. Someone who is eating off the dollar menu often has a penis that can be described as cute. It may replicate an actual normal penis in appearance, although in a pediatic proportion (think mini me). If you suspect your mate is eating off of the dollar menu, you can confirm this with any ruler measuring less than 5 inches.
