Thanks to Lughaidh who "shooed" (sitheadh) me off my incorrect sanas of loogin as "leath-dhuine." Irish "Dh"
turns me into a leath-cheann.

Loogin: Irish Amercian Vernacular term meaning a "fool" or "idiot.

Leath-cheann: a half-wit. (O'Donaill, p. 770)



"Good mornin' Simon...Say listen to this loogin here...What's he doin' tryin' to jazz another jane over the telephone?" (James T. Farrell, Gashouse McGinty, NY, 1933, p. 103.)


It takes a "ceann " to correct a "leath-cheann."

From CARNY LINGO

LUGEN - A really dumb, easy 'mark'.

(Leath-cheann, half-wit)


MARK - A carnival term for townspeople. Particularly, the ones who become their cusomers.

Marc: target.

A wild "mark" who wagers large amounts of money is called a "Mark Anthony" on the west coast.

Marc An-dána: a rash mark
