CAS
1. CAS, short for 'cracking a smile', is a mutation of LOL. Although CAS was originally considered an anomoly, it was found to be a more accurate discription of ones state of humor. Ergo, CAS is now rappidly replacing LOL.

2. Describing ones state of humor to a lesser degree than LOL and concordantly, and even lesser degree than ROTFLMAO.
Me: im telling you a joke.

You: LOL, that was kind of funny. but not that funny.

Me: dont say LOL unless your actually laughing out loud you fool... i know your just cracking a smile!

You: you are right, as always, CAS.
