Edit: For WordWind: I was going to add that yes, things can only be honkin' big, not honkin' small or honkin' smelly or anything else...

well, in a Britslang moment, I'd have to say it would in any case be impossible for something to be honking smelly as 'honking' means smelly.

As in, I think that cheese may have gone off.... oooh, yes, it's absolutely honking.

Frequently also applied to feet.
