Learn to read before posting, and learn to write English, so that you can treat the forum with respect - what is this word "wamma wanna"?
I also used to think that it is the slang but look like this is now acceptable English word to represent the short form of "want to" or "want a".Definition of "wanna" already present in Cambridge and Merriam Webster.
I think it might be informal language of speech but I do not think Forum communication should be strictly bound by formal communication.
@OP. I think you got of suggestion for your want, so start following and working on it because only "want" will not help you to achieve anything.
