This totally happened to me before (sorta) My friend asked me to open her water bottle but it was stuck, then a random girl walked by and offered to open it. She made it look EASY (she was kinda too thin too) and then i said, "I loosened it" I totally had a troll face just then, I GAVE IT AWAY!!!
I claimed this sort of thing about six days ago. Walking around town with my friend and she asked me to open her bottle of diet Pepsi. I was like: "Fine gurl, gives eet." Couldn't open it mind you, but she did afterwards. I had definitely loosed it for her. DEFINITELY.
