Standing for "Unidentified Party Bruise".
the common (but not remembered) cause for this is :
a) running into things
b) falling on your face
c) general clumsiness

These contusions are noticed most likely the morning after, with a slightly hungover expression of "huh?"

"There is a huge U.P.B. on my leg"
