er, what do all these "positions" mean?

I guess I'm not a very well involved fan-girl, but could you tell me what those things mean? Seme? Seke? Uke? I'm utterly confused. Someone? Anyone? Help por-favor?

Seme - the guy on top; the dominant one

Uke - the guy on the bottom; the submissive one

Seke - a portmanteau of the previous two; one whose role varies with the relationship he's in.
