fallon 

v. to fallon = to laugh at one's own joke, especially during the very act of telling that joke.

Origin: derived from Jimmy Fallon, American comedian (b. 1974 in NY)

Sarah couldn't manage to describe Isaac's hysterical story. She kept fallonning and then would try to start over. The 20-second story took about 4 minutes, most of which was her laughter.
