The act of cuddling with a significant other in a bed or other type of area. You then rip a huge fart and wait a moment, then throw the covers over their face and hold it down, so they are forced to smell the awful stench of your fart.
A Techno-House party in a small room with DJ'S. The people on the dance floor create heat and the walls will begin to sweat, creating a hotbox, sauna like effect.
A hotbox is the act of taking a large hit of pot and blowing it up a very good friends vagina in order to get them high without them having to inhale. It is somewhat similar to a shotgun, only there is no danger of the person on the receiving end of the puff coughing.
Hey, hun.. I could really use a hotbox. I didn't wear panties under my dress.
