Сокращения не для общения

Понимать их надо, конечно, а вот пользоваться в речи не стоит:

 gonna = going to, gotta = [have] got to, wanna = want to, gimme = give me,

   gotcha = got you, lemme = let me, letcha = let you, outa = out of,

   c'mon = come on, ya = you, yeah/yep = yes, nope/naa = no, betcha = bet you,

   dunno = don't know, kinda = kind of, lotsa = lots of, lotta = lot of,

   helluva = hell of a, a = going to (i'm a = i'm going to)
