giggle mode 

When someone is tickled so much that if another person even touches them (ex. 5-10 min. after) they laugh hystericly where ever you touch them.

Bob put Sally in giggle mode in class today, I tapped her on the shoulder to ask her a question and she started to cringe and laugh out loud.

gigglemores 

Two or more people unable to stop giggling, typically over something that does not appear that funny to other folks nearby.

"Those two are such gigglemores; they laughed for almost an hour over the word collaborate."
