What is Ha-mother-fucking-ha?
1.
A saying spoken by U.S. Army Drill Sergeants whenever something appears comical to them, due to the Drill Sergeants inability to speak more than two words without cussing, they will often implant curse words in the middle phrases where they have no business being.
Private: Drill Sergeant my knee bone is sticking out of my leg.
Drill Sergeant: Ha-Mother-Fucking-Ha, Front Leaning Rest Position Move!!!
(Translation)
Drill Sergeant: I find your pain and discomfort comical to me and I would like you to do push ups to further increase your pain and vicariously my amusement at said pain.
