lmoof 

A combination of lmao with oof, used alternatively to lmaoof as it is more easy to pronounce (le + moof). Used primarily after recognizing the humor in a situation where you're being mocked, but can also be used to disguise the pain when being mocked.

Jackie: Oh my god you had 5 tries but you still couldn't hit the hoop
Chan: Lmoof, it wasn't my fault, I haven't played in 2 years!!
