Of late, I have been noticing a lot of casual memes floating around, particularly on Facebook, that involve this phrase. Typical constructs could be like the following examples:
B*&^%$# be like...I need a break.
Niner fans be like...but we won five times!
Liberals be like...I hate guns.
I understand these are strictly informal constructs. But I'd need a native speaker's (American English because most such memes seem to originate in the US) take on:
- how casual these phrases are, i.e. if they can be used in semi-formal fiction writing?
- how this usage originate and if it has any affiliation to a particular dialect group, e.g. Midwest, African-American, Southern American, etc.
