Jamming to your favorite music while wearing some extremely rock worthy/incredibly comfortable night clothes. The more the merrier, but also equally as fun when on your own. Add in some air guitar, or air drums, and your Pajammin session is complete.
I was really tired the other night but I just kept pajammin!
-or-
Person A- "Dude, you're still up?"
Person B- "Yeah, man. Once you start pajammin you can't stop!!"
Person A- "Good point. I'm coming over!"
Person B- "PAJAMMIN PARTY!"
is when you "rock out" or "jam" in your PJ's. While mostly common when playing the video game Rock Band, this can also be done playing 'real' instruments.
Henry: Hey, Sean, wanna pajam tomorrow morning?
Sean: Hell yeah Henry! I love pajamming after a sleep over with you!

n. software that is no longer sold or supported by the original publisher / developer, often found as free downloads on the internet because it cannot be obtained elsewhere. Not legal, but often seen as morally acceptable because the company that made it is no longer selling the title, nor releasing it as freeware, therefore abandonware is "keeping the gamealive", so to speak.
Doom II is not abandonware because idstill sells it, while The Incredible Machine is not sold, therefore is abandonware.
