Stands for "I laughed so hard I broke all my furniture"
A long, useless, but more original way of saying LOL.
The origin of the word most likely came from a pothead that thought lol was getting old.

The breaking of furniture doesn't really occur. Just like when one says lol they aren't really laughing.
Guy 1: I kicked a kitten! Ilshibamf!
Guy 2: ilshibamf...? The hell..
Guy 3: Hey at least he didn't say lolx or lolz.
