this is a word- used much like "sweet cheeks
" or "honey buns
" - which is basically a term you use for friends referring to their backside in a jokingly flirtacious
manner. somewhat like "hey, hot stuff
!" you might instead say "hey, tastykakes!" and spank
their backside as you stroll by. this can be shortened to "what's up, tasty?" or pluralized, "hey there, tasties- you guys missed the movie!" however, don't say "hey tastykake!" because this suggests that they have only a single butt cheek.
that new girl looked at me weird when she saw me spank my friend and yell "hiya, tastykakes!"- i guess she doesn't understand it's just something we do with friends around here.
