Tack On

What is Tack On?

Tack On meaning In an informal ceremony, when a sailor is frocked (see above), each of the shipmates in his unit who are already in the higher paygrade to which he is frocked ‘tack on’ his crow by making a fist and pounding on the crow on your rating badge (which is sewn to the sleeve of your uniform). It is considered poor form to ‘tack on’ with more than one pound of the fist; nonetheless, after a number of your buddies have ‘tacked on’ your crow, your arm is generally black, blue, bruised, and extremely sore. A mild form of hazing.
