Right about now, John Mayer is surely wishing he'd used his mouth for a little more singing and a little less candid chatter. Mayer has taken heat today for some crude remarks made in a new Playboy interview. Among other overshares, the singer told the magazine that ex-girlfriend Jessica Simpson was his "sexual napalm."

"That girl is like crack cocaine to me," Mayer said.

But if you think it's in poor taste to discuss the particulars of his sex life with Simpson, buckle up -- it gets worse. A casual inclusion of the 'N' word has launched a flurry of Twitter-apologies, but here at PopEater, we think the racial slur was just the tip of the inappropriate iceberg. After the jump, we look at what Mayer said and why his apology falls short.
