milsplaining (blend word ‘military’ & informal form splaining of gerund ‘explaining’) is pejorative term meaning "(of a squaddie) to comment on or explain something to #civvy in condescending, overconfident, often inaccurate or oversimplified manner"
It is total bravado based on a rigid hierarchy where people have to do exactly as you tell them even if you are an utter knob. Civvies don’t give a shit about rank & will tell you to poke it.
I’m not #milsplaining you thick Civvy twat, I’m giving you guidance based on my considerable military knowledge gleamed from Commando comics & years of mucking other military around. I have zero knowledge of real world but if I shout & point, you will have to do what I say!
