Any and all communicable diseases that can only be contracted in the 43402. Ebola, gonorrhea, herpes, herpes simplex (there's a lot of that), common cold, bronchitis, crabs, mononucleosis etc. If you've got the beeg, you've got it all.
Based off the name of an adult website, Beeg means essentially, big. But Beeg is more than jut big, beeg is massive, colossal, gargantuan. An absolute unit of a human being!
