I'm almost finished with Robert Ludlum's novel THE ICARUS AGENDA, which has two slang phrases in it that have me scratching my head (a lot). "A two toilet Irish detective" is supposed to be American Boston-Irish slang, and I guess isn't too hard to figure out. I still wanna know!
The Cloonchas is the area of Cloonbonnive and Gortaganny in West Roscommon where most townlands begin with 'Cloon', eg. Cloonfower, Clooncan. From the Irish for meadows, 'Cluainte'.
