BSL

Bull shit life.

The 2011 equivalent of FML.
Used to describe such lifestyles not worth the time and effort.

You: Hey ladies. What's up?
Ladies: *Flip the bird*
You: No one fkn talks to me. I'm like a Jehovah in an Atheist neighborhood. I've got a BSL.

BSLS stands for Ball-Stuck-to-Leg Syndrome. it normally occurs on very hot days, or after extreme workouts, where the sicknasty sweat that builds up glues your ballsack to your leg. it is rather annoying and not at all pleasant.

BSL-4

A laboratory that contains the deadliest viruses known to mankind. These viruses are Ebola, Marburg, Lassa, Hanta, Smallpox, Crimean hemorrhagic fever, Argentinean and Bolivian hemorrhagic fevers. So any disease that makes you bleed to death, you should wear a positive pressure suit not to catch it.

Walking into a BSL-4 lab without a space suit is basically a suicidal act.
