Yesterday I told my guy friend that I have been sitting alone at lunch so he invited me to go sit with him and his friends, so I took the offer and sat with them. while all of us were laughing and jokeing he looked at me and said "your boobs jiggle when you laugh." I then covered my face from embarrassment and laughed a little as I said "oh my goodness" then he said ahahhaha " your butt does it too!" What just happened? And what does it mean?
