Sorry, but it doesn't really work as a "mis-spell" or rhyme like, or really any relation to what you mention above -to me.
I was trying to figure out if ng was some abbreviation for a type of furniture (think wicker) - dont ask me why that came to mind, but it did, I just see it a the word straw with 2 non-sense letters after.
sorry & this is only an opinion, take it with a grain of salt - for all I know you will sell it tomorrow .
Good Luck,
