There are always peope playing with language and creating new language to fit voids or be cool/unique. Things usually start off as slang with younger crowds. Your Google and text example are conversions. Words have been kept the same but have crossed word class barriers (noun to verb.) Things usually start off as slang with younger crowds. These kinds of things fade in and out but more prominent ones will stick and become part of the language.
Linguists and Applied Linguist spend their lives studying language phenomenon like this. There are many ways new terms can be formed and they all fall under the heading of morphology. If you are interested, just 'google' morphology + slang
or something like that. I'm sure you'll find more than you bargained for.
