A very firm, concise and unambiguous way of dismissing someone, namely used in a social context and not suitable for the office. Retains a slightly friendlier tone than the sharper variant "fuck off", the latter of which should be used in scenarios where the conveyance of anger is key.
"Please wash the dishes"
"You can fuck right off".
Notice the subject matter here is most likely to be exchanged between persons with a preexisting relationship. If the offending party was a stranger, "fuck off" might be used instead.
(noun) A migratory Canadian rodent, often found rummaging in the dumpsters around Hollywood for toxic scraps to stuff in his leery hideous face. Canuckodile.
me: I saw a canuckodile under the queensborough bridge the other day.
friend: Really, what was it doing?
me: He was experiencing heaven for 15 dollars a man thanks to a dimatoid.
