FTTCL

FTTCL: Flies/flying/flew through the ceiling laughing
WFTTCL: (Somebody) will fly through the ceiling

For example - you fell through the floor laughing so now you're flying through the ceiling below the floor you fell through laughing

My friend: Yo mama so fat she played pool with the planets.
Me: FTTCL!
