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:
Fluffy: I roffled for about ten minutes!

Nutty: Roffle

It is a typo for ROFL. This is used when you are giving the expression, ROFL but much greater.
