Before you correct other people's grammar, make sure your grammar is correct too! It would actually be, " Look, kid, it's 'dumb', not 'dum dum' can you stop saying 'dum dum'? You're probably a 5 year old who wants attention. I think your mom is asking you to take the trash out. Don't forget to throw yourself in the trash too. <33" So, instead of hating on other people's grammar, make sure you have good grammar too! <33
