A philarp is when air enters the male sex organ and is then released out from the tube of justice (the same place the air entered). Originating from the Latin word eximo-viscus. Odor clouds are prominent due to penile disfunction or disease. Also can be compared to a woman's queef .
I was flab stabbing this ho in the back of my hooptie and while I thrusted my spear of might into her nappy dugout I suddenly philarped and out came a gassy cloud.
