VMOL
Literally means "verbal moment of laughter". When you are baffled by a comment in a text message and cannot hold in your laughter, and you must express it verbally, it is called a VMOL.

Often occurs in a public place making you look like a creeper laughing to yourself.

Also resembles the name of Harry Potter's arch nemesis, Voldemort (Vmol)
When the standard "LOL" no longer cuts it, VMOL comes to the rescue.

Liz: VMOL!!
