A serious medical condition where a patient is caught in a state of perpetual or 'over-lolling'. In Lolitus, lol's have consumed the patients entire psyche, causing he or she to poop him/herself repeatedly until he/she dies. This is a VERY serious illness with no known cure. Symtoms include dry mouth, headache, sore throat, LOLOLOLOLOLOLOLOLOLOLOL, constipation, LOLOLOLOLOLOLOLOL, diarrhea, LOLOLOLOLOLOL, and LOLOLOLOL.
If you notice strange bolded LOLOLOLs replacing words on your screen, then you probably have Lolitus. If your friend seems to comment on your facebook with only 'lol', you're probably about to die. In this case, contact your doctor and tell him to give you a prostate exam. Its the only way to survive.
