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."
