Dude, the grossest thing happened the other day... I was out lunch with my G-ma and she gave a dollar to a homelessguy and he had a poorgasm all over her face... lets jus say it wasnt priceless... the napkins cost another two dollars
When a retarded person finds excitement out of something that is so 'poor' (not good). When experiencing a poorgasm the person will shout out 'Poor!!!' in an excited manner.
I have just died in diablo 2, POOR!!! (person experiences a poorgasm)
