Is the definition of lauhged out loud and shat my pants. This frequenly happens when you laugh and feecal matter evacuates your anus and blends with the fabric of your pants. LOLASMP should not be mistaken for the less acute LOLASMB (Laughed out loud and shat my boxers). A LOLASMB may be contained in the boxer the hole day and no action to clean up need to be taken.
I went to my girlfriends house to eat dinner. After the dinner she told a joke and i LOLASMP.
