gabenella - Two people who are fighting like cats and dogs but will end

Two people who are fighting like cats and dogs but will end up married because they’re too stubborn to back down

Those two are a gabenella. They’ll argue until they’re old and grey.

My neighbors are a gabenella. They throw things at each other but still live next door.

My friend and his rival are a gabenella. They’re gonna end up stuck with each other forever.
