An unpleasant infection causing people to snore abnormally loud. Often caught at large gatherings such as music festivals from lack of sleep and close contact with large groups of people.

Top Definition

A very unpleasant and undesirable disease; used in comparisons to express the even greater unpleasantness and undesirability of the object to which it is compared.
Simon Amstell (presenter of the BBC show Never Mind the Buzzcocks): "Amy, why don't you do something nice with Katie Melua?"
Amy Winehouse: "I'd rather have cat aids, fank you!"

A disease you can get only if you are a cat.
One cannot get this disease if the cat piss on one's hand seeps into a nearby cut.
Simon Amstell is making his cat aids joke. (laughter ensues)

usually followed by the term LOLOLOL when laughing at someone who's cat died tragically of a sexual disease (ie. aids). To avoid anger from the affected person, the 'laughter' generally covers up by typing LOLOLOL abroad on a foreign computer (for example, a Spanish keyboard)
*a typical internet conversation*
Anna: What's wrong?
Joe: my cat
Anna: What happened?
Joe: it died of aids today
Anna: Sorry, spanish keyboard, can't write properly
Joe: Sure
Anna: cat aids LOLOLOL xD
Anna: sorry urgh
