(abbreviation) In short, SUCK A DICK. In long-speak, the condensed, shorthand sequence of print heralding defiance, contempt and disgusting indifference stopping short of outright hatred to its intended recipient Simplistic, straight to the point, and more oftentimes than not easy to translate without any previous exposure to the sequence. Coined, created and transcribed by well known International Phrase-coiner and Exhibitionist N. Nick in his successful attempt and creation in producing in abbreviation that was sincere and heart felt degradation to its intended yet remaining not overtly profane and blatantly vulgar to nearby witnesses.
Touring some of the town’s more seedy and dingy parts John and Paul amused themselves as they attempted to decipher and interpret some of the local color bursting in multiple colorings and shadings. “Ehhhhh” sang John, in that absolutely aggravating as Fuck English accent everyone seems to notice, “Wonder wot that over there in red and black paint is supposed to be about?” Reading it aloud he began “S-a-D” seeming to make his reproduction sound like a question. “Shit, you’re such a dumbshit, John, ‘Suck A Dick’, Muthafucka, what the bloody hell’s wrong with you?” Paul asked noticeably aggravated and impatient. “Suck A Dick, Suck A Dick, Suck A Dick… Suck This Dick, Jesus-fucking-Christ already. Suck A Dick, John. Go fuck-all, muthafucka”.
