Techniques in Flirtation While Texting: "lol, jk"

Every guy has been in this situation. You're texting (or facebook chatting, if you're a fan of ineffective methods of communication) a girl, presumably one who you would take out back and with whom you would "enjoy some good old-fashioned American fun." (c.f. Meg, Family Guy, "Barely Legal", 2006) Oh yeah, it's like that. A very attractive young lady, if that thinly-veiled sex image was too subtle for you. Suddenly, she says something to you which sets off one of the flags in your brain. For example, she might utter something along the lines of "yeah, ever since i started track i think my butt has gotten tighter." Now maybe she's in the small demographic of girls that won't realize she just set off the sex bomb in a man's brain. But in all likelihood, she thinks that the text above is an innocent statement, only having to do with her fitness, and not with that "little tight ass" (c.f. Kanye West, "New Workout Plan," 2004) But you, as a guy, want to let her know that you respect her chiseled gluteus maximus, but at the same time, are not a sex deprived pervert. So what do you do? You say, "i think it's plenty tight," and then you add the bitchiest phrase a man can ever type: "lol jk."
I understand the thinking. You want her to know you have urges, but at the same time, don't wanna come off as too forward. But I will tell you now, typing "lol jk" in any circumstance is the manliness equivalent of shaving your legs. Just don't do it. If you two are close enough, she'll take your sex joke as just that: a joke. And if she doesn't: fuck that bitch, get money. (Hasn't Lil Wayne taught you anything?)
"Lol, JK" is a very useful phrase: it lets you reveal carnal desires while covering all your bases by veiling them in a joke. I get it; I've done it. But sometimes, you gotta just let your balls hang out there, and say what you want, bruh. Yeah, sure, it may cost you some girl that may be in contention for the coveted ten rating, but the honesty will get you many more (albeit less attractive) girls in the end. And in the words of Juelz Santana, "Two nickels make a dime every time." (The Bad Side, Lil Wayne feat. Juelz Santana, The Carter 3 Mixtape) End of tale.
Moral of the story: Let yo balls hang, dog.
