America has fought two wars against the British and won twice. If we want to pollute the language with whatever nonsense we choose, then I think we have earned that prerogative. Scoreboard, Baby!
It's a neologism. It's an ugly neologism but to say it's not a word isn't accurate. Americans understand it. Other English-speakers may repudiate it but within the confines of the US they can use it as they see fit. While I'm at it though, I must say I'm concerned when some American neologisms get picked up by other English-speakers. Nothing I can do about it but it grates. "Dove" for "dived" is just one of the annoyances. "Snuck" for "sneaked" is another. Even mainstream journalists in non-American-English publications are using them. And then there's the verbalisation of non-verbs (a lost battle that one).
America only invades places that are nice enough to keep. Otherwise it is an incursion or a trespass.
There are verbs which are both regular and irregular. Burned and burnt, spelled and spelt, learned and learnt, dreamed and dreamt etc. Usage depends where one comes from and either is acceptable. I have always used dreamt, burnt, spelt, learnt etc. I teach ESL at quite a low level. During pronunciation practice I ask my classes which is easier to pronounce. 90% will say dreamt, learnt etc is easier.
