LSFHIC 

Acrynom for "Laughing So Fucking Hard I'm Crying"

Internet slang to help save time when typing
"NightStalker": posts something very funny on a forum
"corporate_lackey" reads it and finds it so funny he starts laughing uncontrollably until tears are literally rolling down his cheeks, but he cannot find an emoticon that proper expresses how he feels, so he simply posts: LSFHIC
