The act of experiencing an
erection, in such a way that it causes the pants or shorts to form a tent
like shape at the front, because of the raging
erection that is experienced by the person wearing the garment.
1) I felt myself pitching a tent as I saw the
girls walk by.
2) "
Dude you just pitched the biggest tent while you did your presentation to the class." "Yeah I know, I tried to control it but of course that didn't work."
