If you want to prepare your guest, you could say something like "Oh by the way, my mom can have kind of a short fuse sometimes, not to guests or anything, but sometimes she just really blasts me or my dad. We don't take it seriously but I just want to warn you in case she goes all Stalin on one of us. We're used to it."
If one of my friends said this to me I would be even more excited and looking forward to dinner for the sheer entertainment of it - I mean if they "dont take it seriously", it is fair game to enjoy it, right? My family is totally loco fwiw.
