A useless or worthless person that has married into your family.

An 'in-law', that is basically human garbage.
The only drawback about Christmas dinner at my place is that although I love my sisters coming over, all the fucking bin-laws will be here too, talking shit and pissing me off all day. I wish I could stuff those two worthless chumps instead of the turkey, because the turkey has more intelligence than both those pair of little shits put together.

Happy Holidays!
