I'm merging the above definitions unless someone can find an example that means large but not in an intimidating way. Davilla 05:57, 21 April 2006 (UTC)
# To go to hell, to disappear, to screw oneself.
How are these even remotely related? It needs a rewrite but I can't touch it. I wouldn't know what to do with it. Could someone please revise the defintion? Davilla 06:20, 21 April 2006 (UTC) you can settle a bit now.Goodbizz (talk) 21:38, 31 January 2013 (UTC)
The lexical ambiguity of a word or phrase pertains to its having more than one meaning in the language to which the word belongs. So the phrase "fuck off" can mean in a sentimental way "no way dude" but also in anger with disdain to negativity towards oneself "get the fuck out of here" or fuck off in a nut shell.by Goodbizz (talk) 21:37, 31 January 2013 (UTC)
It being a phrase widely used across the globe can have so many levels and and sentiments it has in its own right its own ambiguity.
In the UK and Ireland at least, "fuck off!" can also mean "no way!", i.e. "I don't believe you!".
The adjective version appears in British slang, and appears in dialogue in Lock Stock and Two Smoking Barrels ("Also, I think knives are a good idea. Big, fuck off shiny ones.") Ritchie333 (talk) 14:25, 23 January 2013 (UTC)
