S.B.D. 

Silent But Deadly! unfortunately an all too familiar odor eminating mysteriously around groups of people, survivable outdoors, but toxic in an enclosed space, in which everyone looks around trying to figure out who let rip (even the smirking perpetrator).

sitting in the back of a pick-up truck with a group of friends on our way to lollapalozza, when suddenly the driver's side window rolls quickly down and the driver sticks his head out the window screaming "S.B.D.!S.B.D.!" dousing the front cab with ozone, while the guy riding shotgun is laughing his guilty arse off. if especially deadly, DO NOT be stuck downwind, i.e. in this case, riding in the back of an open truck slowly, or worse, trapped in the car itself.

S.B.D. 

Stupid Bitch Disease - A mental condition (often inherited and semi-contagious) that strikes approximately one out of every three women in their early twenties. Symptoms include sudden and rampant sexual promiscuity,
compulsive lying, erratic mood swings, excessive and frivalous nagging, manipulative behaviour, and all-around evilness. Although there is no known cure, the condition usually lasts only 6-24 months and can be treated with bitch-slap therapy. Some acute cases, though rare, may develop into C.B.D. (Crazy Bitch Disease).

My friend has been really stressed out since his girl caught S.B.D.

Post Traumatic Spring Break Disorder (P.T.S.B.D) 

The realization that you have to go back to doing the same ole shit after a week in paradise.

-You think you hear your friend doing a beer bong in the bathroom

-Wake up and throw a towel over your shoulder and head down to the pool that doesn't exist

-You find your hotel room to look exactly like your room at home

Bro 1: Ayyy brah I woke up this morning with a kink in my neck, was gonna head down to the hot tub to straighten it out.

Bro 2: Yo bro, we aren't in PCB anymore, we dont even have a hot tub! You must be suffering from Post Traumatic Spring Break Disorder (P.T.S.B.D)!
