Pocklet
A food or treat that is unexpectedly filled with a sweet substance; most often chocolate, but can be jelly, cheese, etc. Within one food item, there can be one pocklet or many, it does not matter.
"Wow! This croissant has the most amazing flavor pocklets!"
pocklet bar
A chocolate bar you stick in your pocket, is forgotten, becomes a melty mess packet of goodness and is then found usually at the end of the day or when your wife checks your pockets before putting them in the wash.
eg. "Tim you shouldn't put that chocolate bar in your pocket, you know you will forget and it will be a pocklet bar by tonight."
