Military slang. Roughly: "to get fucked" or "fuck you." Also: "Fuck it."
Origin: 35th Infantry Division (Kansas)
National Guard deployed for the first time since WWII. The "Santa Fe" Division, named for
the Santa Fe Trail that settlers followed across Kansas from the Eastern USA to New Mexico, immediately began to break down relationships across Central Command and generally treat the subordinate units with derision. Since then Guard, Reserve, and Active Duty units which were under
the Division's command have used the motto in this way.
