lbeasp is similar to the definition of ROFL, only it does not involve one rolling on the floor with laughter. It has the same principles as a ROFL however only missing out the rolling part. The Letters of LBEASP mean:
Laughing Beyond Epic And Safe Proportions (respectively)
This means one may be laughing so much that they are no longer able to function their lungs in the correct manner at that precise moment due to excessive laughing.
Ganjusan: Hey doyle I am laughing beyond epic and safe proportions.
Ganjusan: LBEASP my son, LBEASP
