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."
