get your crumbs at the ready 

Preparing to make fun of somebody, hence the term "crumb," which means to make fun of. The term parodies medieval battles with archers getting ready to fire at their enemy.

A completely unattractive chick walks by and two guys are trying not to laugh.
-"Oh God..."
-"Get your crumbs at the ready!"
And away they go teasing her deliberately.
