For my style this is way to forward. How do you usually game? If you're a really high energy direct PUA this might work, but that's probably with the right smile and body language. I'm pretty low energy myself, so I've never tried this. IMHO this is to forward. Image a gay man coming up to you checking you out, walking up to you and go: "You look good, you DTF?" Would be pretty strange right?
You could incorporate something like that in your daygame perhaps? Chat up a girl and go for a # close. After you get her digits you could insinuate that you're planning on calling her up for a night on the town and on top of her... Let me know if that works, 'cause that'd be cool
