This word originated from the abreviation :
ROFL = Roll On Floor Laughing.
Which is a term widely used in internet chatrooms and instant messaging software.
Roffle evolved due to people readling ROFL like a normal word rather than spelling out each letter as R. O. F. L.

Roffle is therefore the casual friendly way to say ROFL and can be used as a verb in its own right:

A polite term for shoving a lubricated probe into the Earth's hole to release gas.
