Just have one of those Smarties bar filled with Pop Rocks!!
Steph and I each just had a piece, and we let it melt in our mouths. I began to giggle. I walked up to him and opend my mouth near his ear *pop rocks noise* LOL. He also opens his mouth to my ear "air kiss style", and then we're both laughing our asses off like 7 year olds! We kept going back to making supper, then as the popping got louder we kept doing the Pop Rock Air Kiss and laughing like complete fools LOL I hadn't had Pop Rocks in sooo long... I didn't remember that they popped that long hehe.
