KB

Those who are getting mushy use KB to mean "kiss back." This acronym's most commonly sent in response to K or XOXO, to return your affections.

BFs, GFs, and other SOs are most likely to send and receive KB. You may also receive KB in messages from your mother, father, siblings, or grandparents, if you're part of a family that is comfortable showing affection (how bizarre).

Those who are relaxing may use KB to stand for "kick back." This acronym is meant to conjure a picture of someone sitting back, kicking up their feet, and chillaxing.

For example, your friends might use KB when asking whether you want to come over for a chill hangout. Or, your SO might use KB when asking whether you want to stay in tonight, rather than go out on the town.
