sudden jihad syndrome (SJS)

A feeling of sympathy for al Qaeda that inspires local terrorists to carry out attacks on the U.S., even though there was no previous affiliation between the groups.

Sudden Onset Autism 

Sudden Onset Autism, or S.O.A for short, is an extremely rare condition of unknown origin. Development of this disease is both abrupt and severe. As of now, the pathogenesis and mode of infection have eluded even the most qualified of research teams at Harvard, Hopkins, and Yale. Some have suspected that transmission occurs through contact with an infected person, especially prandially. There is still hope for a cure, although we may be decades away.

Infected Person: Hey man, let's go grab some lunch
Healthy Individual: what?! It's 3 in the morning. What's wrong with you
Infected Person: Well... it's lunchtime somewhere!
Healthy Individual: Oh God, you have Sudden Onset Autism... Please go away from me!

Sudden Brazilian

1. During the act of sexual penetration with a female, the male pulls his penis too far out of the female's vagina, and accidentally rams it into her anus instead during the next thrust, accidentally having anal sex. Usually VERY unpleasant for the female involved.

2. Also could mean the sour/surprised face one would make when being rectally penetrated suddenly.

1. "Man, I was so drunk last night, when she said push it in harder, I pulled out too far, and gave her a Sudden Brazilian."

2. "Why the Sudden Brazilian face? You suck on a lemon or something?"
