There is in fact an entire small meme culture of "five feet eleven and a half inches vs six feet" based on the absurdity of this, yes. you can probably get away with being 5'10 or especially 5'11 and lie to say 6' without issue unless you are in fact dating a taller than average woman. But if you get to the point of meetting up that probably won't matter.

You can only lie to some extent, though. hard to pass off 5'8 as 6'.
