Other uses are tricked out ie blazoned ornately like a coat of arms. Old Eng. trick: a trait, feature or characteristic peculiarity. A heart too capable of every line and trick of his sweet favour
It’s odd how much slang we never second think. I wonder if this also explains the more obscure “How’s Tricks?” The Urban Dictionary claims both uses of Trick were derived from prostitutes, and I guess I can’t blame them for backfilling some folk history.
