cracking up

Bursting into a prolonged fit of intense, uncontrollable laughter. Instigating this sort of reaction in someone is called "Cracking that person up."

John told me a hilarious joke the other day and I started cracking up.

cracking up

when you cracking up it means you laughing so hard at stupid and retarded shit people say or be doing....and most of the time people is hating you so badly and want to sabotage everything you do and be so evil to you because you so far out their league they cant stand it. and do everything to bring you down and always end up in prison forever or dead the worst way possible like being burn alive.
