Wiktionary is a good place to look. "getcha" = get you "betcha" = bet you Never seen "meetcha" before, but it would mean "meet you".

Those words won't turn up in a dictionary. They are informal words that you don't use in writing, but people use it to talk to each other, because they don't need to say every word clearly. There are other examples like, kinda = kind of, gotta = got to.

Hi Olga: getcha, meetcha, betcha are all very casual and informal words. I getcha = "I get you" (i.e. I understand you / I understand what you are saying). I'll meetcha = "I'll meet you" You betcha = expresses agreement, like so "Hey, you want to come over to my house later?" "You betcha" I hope this helps.

These words are a quoted form of common oral speech, much like 'wanna' is the spoken form of 'want to'. These forms are often heard in informal spoken speech. The actual words they represent are in the dictionary, but these are not.

thanks to all for the help! this is a useful information for me.
