A mini hard-on. Gotten when aroused in a place where you probably should not be aroused. You body won't allow for a full erection, so you feel a stem grow in your pants.
I was telling my boys about this hot chick that bent over in church, and I could see her tramp stamp. My bud asked me if I caught a stem. And I said. No doubt!

A small glass tube with a plastic lower inside sold at gas stations bought solely for the purpose of making a crackpipe.The flower is thrown away and a wad of mesh,usually copper pot scrubber is stuffed in one end.
I just hang out at the dope hole with my stem and catch smokers on the way out and smoke for free because they dont have the balls to carry a pipe on them.

pieces of plant in dried marijuana that cannot be smoked, must be taken out in order to keep from making holes in the rolling paper/blunt wrap before smoking.
Be careful to take out the stems, they'll ruin all the hard work you put into rolling your blunt.
