An abbreviation for "obligations," generally used by / in reference to people too lazy to fulfill their obligations (and too lazy to even say the word)
Man, I'd totally hang out with you tonight, but I have a shit-ton of obs to stay at home and not fulfill. I wouldn't be able to handle the guilt of not leaving the time slot open for possibly getting around to doing them...I've at least got to stay home and hate myself for being so useless.
Person B: "Calm down, Mr. OBS."
Player2(host): gg hf gl
Player2 then starts game.
Hiphophead2 : "He's still a lil bitch"
Hiphophead1 : "Is your mom on her way home?"

Hiphophead1 : " Im just askin bruh, I wanted to spark this blunt so you can hear this OBS track and understand where im coming from,"
Hiphophead2 ; " Nah shes in cali , light that shit sonny"
*Ignites the Mary
Meanwhile........ Moms back early, While unloading groceries in the kitchen, and catches the ever pungent scent of Gods gift of sativa,
*Knock, Knock, Knock
Hiphophead1 : "huh?"
Hiphophead2 : "wuh?"
Just then, MOM KICKS THE DOOR IN, HER EYES ARE WHITE AS THE SKY, SHE CLUTCHES THE WOMB THAT ONCE HELD THIS DESTROYER THAT IS MAN. FALLS DYING TO THE FLOOR AND MUTTERS OUT HER LAST WORDS....
Mom : "Oh....BeeEs"
