jb

Jason Becker, one of the greatest guitarists ever. He started the speed metal band Cacophony along with Marty Friedman.
Now he's got ALS (Lou Cherigs disease, he's paralyzed), still, he continues to write beautiful music with the motion of his eyes and chins.

JB should stand for "Jason Becker" and not "Jonas Brothers". Nuff Said.

JBS

Just Being Silly - Similar to Just Kidding JK, and Just Playing JP, with a slight tweak, where JK and JP may IMPLY anger, Just Being Silly communicates that any joking was at his or her own expense.

Example -
Prosecutor: Ladies and gentlemen of the jury, as my witness has clearly expressed, with audio playback as proof, the defendant CLEARLY said, and I quote, "I will fucking kill you!"
Defense: Objection! Your honor, my defendant was Just Being Silly!
Judge: Order in my courtroom!

Synonym - Just Bull Shitting, not to be confused with Just Being Silly*
