"Sitting In My Chair Laughing" This acronym relpaces 'ROFL'. because honestly who's really going to roll on the floor from laughter?

SIMCL is an internet acronym for Sitting In My Chair Laughing. A variant on the acronym "ROFL". SIMCL has been hailed as the more realistic description of what someone is actually doing when they use the term ROFL, that is, they are most likely not rolling on the floor and typing at the same time but sitting in their chair and laughing.
