Minging is a word that has it's origins with the British Army, It started to become mainstream around five years ago.
With regards to the word's meaning it is most correctly applied to an object that is dirty but can also mean drunk, disgusting or ugly. I can also be replaced with
gipping,
gopping,
gouting or any other word ending in "ing" as it's not the syllables but the rthym that are important here.
"Your boots are minging,
your plumes in shite,
Your balls are swinging from left to right...."
or; I'm minging drunk, let's get mingining,
but also "Euchh, your locker is full of
ming!"
even...I
shagged this right hippocrocadilapig, she
yas minging!
