At first when he learnt it (because I say it to the cats, quite a lot ) he also used it to mean "come here", and it's also a bit of a blanket phrase meaning "take that away", "I'm not eating that" etc etc.
However, it's getting far too overused and it sounds quite rude (he really says it like he means it.) Should I try to train him out of it or will it just be a phase? I don't want him to know it annoys me because he'll probably go for it even more...Any ideas?
