when you have something to eat and it's not satisfying you can describe as not touching the sides, can also be used to refer to a loose orifice

An unfortunate genital mismatch. Either the woman's vagina is too loose or the man's penis is too small/thin, hence 'It didn't touch the sides'. Also used to disparage a woman by suggesting she has been too promiscuous.
