When the girl you are making out with just got done giving another guy head.

the wafting smell from one stall to the next that occurs while moving one's bowels in a public restroom.

what smokers emit from the end of there cigarettes/mouth. people will say that second hand smoke or "sidestream smoke" is more dangerous than firsthand, true bullshit at its finest. the smoker is getting both second hand and first hand smoke, and the filter doesnt really make the smoke less bad for you. how can someone walking by be more dangerously exposed than someone who is puffing on the dam thing?! smells pretty bad if you ask me, but you need only walk 10 whole yards away to avoid it.
