din

din - v. - to assail with loud continued noise; to impress by insistent repetition

I know there are a ton of words I've never heard before, but this one is so small and so simple that it seems like we'd use it all the time. I intend to din (someone/something) today just so I can say that I did. I voluntarily give up my "din"ginity.
