Peeing over the top of one's waistband rather than through the zipper, using the penis like a hose. Usually done at a time of rush leading to a high pressure relief, thus the fire hose.
Nick: Hey man, did you make it to the bathroom in time?
John: Yeah dude but I was wearing these stupid button up jeans so I had to firehose it so I didnt piss myself

When a redhead is giving you head, and your about to cum, you take your dick out of her mouth, cover part of your hole and spray your cum on her hair. Also could be done during intercourse.

The feeling when you know you will have a liquid shit. As you sit down on the toilet it is already starting to come out and the longer it goes the better you feel, spraying out with such force you could put out a fire.

when a guy pees in a hurry and forces the urine out faster than the normal pace it would flow at. usually in an attempt to quicken a trip to the bathroom or because of an unbelievable and urgent need to piss.
Dude, I had to walk home from school in the rain. As soon as I got through the bathroom door, I was firehosing like a motherfucker.

The man annals the woman and after a period of time spits on her back. The woman, thinking that he has ejaculated his manly fluids turns to face the man. The man then ejaculates his manly fluids for REAL and sprays all over her pretty face. She is now either turned on or extremely pissed off.

After fajitas night, Willie went upstaris and laid an impossible firehose in his toilet. He had to break it up with his brothers toothbrush before he could successfully flush it.
