Cells that maintain the ability to replicate them selves as well as form other cells of the body.
Two major classificiations exist; embyronic stem cells which are totipotent or pluripotent and can make any cell of the organisms body and adult or tissue specific stem cells which are multipotent and can produce only a limited range of cell types.
Often confused by the laymen and stupid right-wing politicians as tiny little babys but really more similar to dandruff than babys.

Maybe if we said that some gay french muslims were using diabetes and parkinsons to terrorize christian evangeslists he would athorize 200 billion dollars and 2000 cell lines (or paa-tench-al persons 4 u Dubs), (though at 50 trillion cells per dead GI we should really get around 100'000 trillion stem cells)

Unintentionally or accidentally getting an erection. This usually occurs during inopportune moments such as during a business meeting or when guys (gay or straight) are playing sports together and make physical contact with one another. It is often considered to be embarrassing to everyone involved. It most often happens to guys when they are going through puberty because hormones are raging out of control and erections happen even when the guy is not thinking about anything sexual.
Guys in locker room after showering after a football game:
Tony: "Dude, are you gay? Everyone noticed you had a boner in the shower."
Derek: "No, man, I couldn't help it. It was just unintentional stem."
