Nipsy Twitch

That unnerving feeling when something has gone horribly wrong while doing work and your anus tightens up in a flinching and constipated way. It's a form of panic attack when you realise your life / career just ended and you go into a wild panic to try rectify the situation before you get found out.

Boss: While you're updating all the systems, if it goes pear shaped, don't have a nipsy twitch, just get it fixed!

Worker: I hit the red button instead of the green one and suddenly felt my nipsy twitch.

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.
