Just Pissed My Pants used to express excitement or laughter. As in the term "What a pisser" which originated back east. Just Pissed My Pants is a way to say LOL or very funny and was originated by Mr. Jody Sigmund during a text message conversation. Not to be confused by the acronym JPMP Just Pooped My Pants which is actually not very funny at all.
That was so funny I JPMP!
