Can you give an example? I've never noticed that (except for certain specific dialects and slang) but I may be blind to it.

I hear it most often with "real": it is real bad, good or weird. The Offspring wants you bad.

Oh yes! This works with other intensifiers as well. "Crazy good", "wicked bad", "mad smart", etc. To my ears, eliding the -ly changes the meaning from the literal reading, to specifically the intensifier reading.

"Think Different" "That went perfect" etc
