More in our series on the reality of MSM (men having sex with men). The following are two entries in the online Urban Dictionary for “Power Bottom.” The “up” versus “down” refers to online votes for or against the slang definition offered (up for “love it”; down for “hate it”):

2.    power bottom     797 up [love it], 41 down [hate it]

While a bottom is usually submissive to his partner, a power bottom enjoys maintaining control over the top and/or the penetration, the normally dominant role in gay male sex. Power bottoms supposedly have skilled tongues. (They give the best blow jobs [fellatio] and rim jobs [analingus].)
