It's what you do when a stipper tells you she is getting off dancing for you. In order to prove she isn't faking it you have to give her the swag drag. The swag is rubbing her pussy with your index and middle finger to make sure she is wet and then drag your fingers under your nose to smell that sweet cunt juice.
Kyle: Aww dude did that stripper tell you she was getting wet dancing for you?
Randy: Yea but I gave her the swag drag to make sure she wasn't fucking with me to get more dances and money.

Kyle: Damn I didn't know hoes here freaked like that. We better get a couple bottles and a private room to pound some pussy in.

When a stripper/prostitute says your making their pussy get soaking wet, and you shove your hand into her panties to drag your finger across their pussy to make sure their pussy is really wet. The word swag refers to their pussy juice. Usually strippers don't like it too much.
Stripper: *moans and shakes her ass* Ooh, my pussy is gonna be dripping for hours, baby, your big cock make my cunt turn soaking wet!
Guy getting a lap dance: Time for the swag drag! *swag drags*
Stripper: What the fuck are you doing asshole!? I'm already waving my tits in your face, what more could you want you horny fuckhead!??!?
Guy getting a lap dance: *finds that her cunt is drier than the Arizona desert in July* Hey, what the fuck, you ripping me off, stupid bitch!
Stripper: I'm gonna file sexual harassment on your ass, fucker!
Guy getting a lap dance: Hey, next time I'd appreciate a little honesty while I'm gettin off. First you lie about your waist size and your tits, now you lie about your pussy being wet. I'm done with you, cunt.
