Disco Patch
In EMS, the Disco Patch refers to the usually tacky, yet highly sought-after golden patch that Paramedics get to wear as a result of completing their two-year training program. It is named as such due to its garish, sparkly colors and bright red lettering. Known for corrupting the hearts and souls of formerly kind EMTs, slowly converting them into a dreaded Paragod, just as the One Ring converted its slaves to Nazgul.
I've been a paramedic for six years, but I still get a little bit hard whenever I put on my uniform with the Disco Patch.
