GGG: Good, giving, and game. More specifically that you strive to be good in bed, giving of equal time and pleasure to your partner, and game for anything within reason. That means being up for trying things you may feel neutral about if your partner's into it. It doesn't mean having to do things that make you feel bad or scared for your safety.

Breeders: Straight/heterosexual people, regardless of whether they have actually reproduced.

Santorum: "That frothy mixture of lube and fecal matter that is sometimes the byproduct of anal sex." The term dates back to a 2003 Savage Love column and was the winner out of more than 3,000 submissions. It honors Senator Rick Santorum (R-Pennsylvania), who, Dan noted, had "compared consensual gay sex to incest, bigamy, adultery, and 'man-on-dog' sex."

Campsite rule: For older-younger pairings, the idea is simple: Leave the younger partner better off than you found them. Don't get them pregnant (or get pregnant by them); don't give them a sexually transmitted infection; don't lead them to believe it's a forever thing; and do support them in their sexual exploration by helping with their knowledge and confidence, and treating them well.

CPOS: Cheating Piece of Shit. This is not the same as someone who is honestly non-monogamous. Being a CPOS is not about having sex with others, but lying about it.

DTMFA: Dump the Motherfucker Already. In a truly terrible situation, it may become DTMFA! DTMFA! DTMFA!

Fuck first: Dan's advice to have sex before a big event, whether it's your own wedding ceremony, a heavy Thanksgiving dinner, or Valentine's Day dinner.

HTH: How'd that happen? Dating back to a 1999 Savage Love, HTH references the way some readers cast themselves as "passive players" in their sex lives, describing something they claim to not know how happened but that they almost always ended up enjoying.

KROK: Karmic Rule of Kink, described in a column from a young woman who considered breaking up with her foot fetishist boyfriend after he came clean about what he was into. Dan said that the KROK "goes something like this: 'Dump the honest foot fetishist and you will marry the dishonest necrophiliac.'"

Monogamish: From a 2010 column, the term refers to a relationship or marriage that is mostly monogamous but sometimes (and by agreement of everyone involved) isn't.

Pegging: Reader-nominated slang (dating back to 2001) for a woman having sex with a guy by using a strap-on dildo to penetrate him.

Saddlebacking: Inspired by the name of Saddleback Church pastor Rick Warren (who has long espoused conservative ideas about homosexuality and same-sex marriage), this 2009 reader-nominated term refers to "the phenomenon of Christian teens engaging in unprotected anal sex to preserve their virginities."

Tea and Sympathy Rule: This rule is for the younger partner in a younger-older pairing. The idea is that if you have been treated well and not been wronged by the older partner, then "when you speak of this in future years... and you will... be kind" (this line is from the play Tea and Sympathy, hence the name). Don't be cruel in your recollections and don't try to damage the older partner's memory or reputation.
