Jello?

A cocky or over confident way of saying hello on the phone. Also when trying to seem laid back or impressing someone with overconfidence on the phone.
(ring)... guy: one sec. hold on.

Guy: Jello?...yes..ok thanks.

Girl:who was that?

Guy:Oh just the casting department for a new movie. I got the lead role.
