The act of extreme tickling wherein the tickler bends the middle and ring finger down on both hands and secures it with the thumb (leaving the "rock on" fingers remaining tall), and proceeds to jab the victim on both sides of the ribs at once.
A key component of this style of tickling is that it is accompanied by the tickler making a machine-gun type noise with his or her mouth while attacking the ribs in a staccato-fashion with the fingers kept straight.
(caution: It is very rare to receive this style of tickling and remain standing, or walk away after an attack without having peed your pants.)
"Watch out, Amber because Dad is in the tickling mood. I just saw him dystermite Andy for five minutes straight."
"Who wants a Dystermite?" - said by tickler in a group of children, usually while jabbing dystermite fingers in the air and making the accompanying dystermite noise.
A portmanteau of hysteria and epidemic, this word is for use by those of us who like to believe in the slight possibility that not everything in the world is going to hell. Whenever there is mass hysteria (by either gender) about some topic of concern that's been blown out of proportion, this word can apply.
The whole thing about wheat being terrible for everyone is a hysteridemic! Just because some people have a disease that means they can't eat it without getting sick doesn't mean it's a a bad food!
