Local to the West Coast of Scotland (especially Glasgow) & having been used since the late 1960's/early 1970's to describe in slang terms, the act of head butting another individual (see also Malky)
I'm led to believe that it's also been used in printed stories & rhymes, again locally in the Glasgow/West of scotland area, by the likes of the Glaswegian poet & wordsmith, Liz Lochhead, (who was invited to read some of her work to my schools drama classes, during the school year 1981 - 82).
"...Ho, see that dobber over there that's lookin at me oot the corner o his eye, he's gettin a dose o the malkies afff a me, if he doesn'y gee it a by."
Kind, brave, loving and loyal. Never EVER let markiela go you will regret it! So ya they a pain in the ass but I makes them more fun and interesting. If you ever meet a markiela I means you met a fallen angel from heaven! If you were EVER rude to them they will piss you off or kill you! Physically and mentally........ good luck !
Guy one: Markiela you are the devil
Guy two: no she’s a lost angel
Guy one: what
Guy two: just don’t be mean!
