Maybe it was induced by the shorthand we'd read for years off Necco Sweethearts, but according to AT&T, Valentine's Day is the most popular holiday for text messaging. From February 13th to the 14th, there's a 33% spike in texting traffic. Yes, you know what that means. The cellphone owning population is trying 33% harder to get laid than on a normal day. For a full list of officially sanctioned booty call shorthand, hit the jump. We don't recommend a single, nonsensical letter of it. No one ever made out after calling someone a QT. (But if so, let us know in the comments. We may have expensive jewelry to return).
