Like maybe your brother bites his biceps after every arm workout.
Or maybe your sister sits in the car doing nothing for an hour after she gets home.
Perhaps your mom eats the same thing for breakfast every morning and takes a picture of it every single day.
Or perhaps your cousin takes selfies every time he takes a poo.
So tell us their weird habits that make you laugh — and we welcome pictures if you have them! Share them via the Dropbox below and you could be featured in an upcoming BuzzFeed Community post!
