A morning erection usually alleviated by urination. Usually dry-humping or twisting around your dick would feel good in this instance. And, when you urinate, you need to do a handstand or pull it down. Even if you do these things, your urine will definitely go everywhere, since morning pisses usually include piss flying everywhere randomly, even disobeying the laws of gravity because of what I can only guess is dick boogers (eye boogers, but in your dick hole).

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.
