Knobyoulater

A casual slang term used to say goodbye to person. Ususally to a hot woman after she has shot a guy down in flames when trying to pick her up. A way for the guy to say goodbye and leave the option for her to come back for more of him. He's basically saying, I lost out no, but I'll knob you later (perhaps when she's a bit more drunk).
The term is catchy enough for guys to say to eachother in brohole kind of way.

Her: I'm outta here loser!
Him: Sure babe, knobyoulater!
Her: Asshole!

or:
Him: I'm out of here mate.
other Him: Sure dude, knobyoulater!
Him: Sure, if we both luck out.
