bullshit

1. Euphemism for most definitions in this dictionary.
More or less everything that the uneducated and incompetent try to express, usually by stringing simple words into several, which they then call sentence. Analyses will not find thought, true opinion or fact in those "sentences".

Alas, bullshit cannot be wholly avoided, it is so prevalent. Bullshit exudes boredom and annoyance, both major vexations for the cognoscenti!

2. Term for beending a conversation by so denouncing the last utterance of your conversation partner.

A: "If it weren't for so much bullshit on "urban dictionary" I would enjoy browsing through their entries."
B: "You uppity know-it-all!"
A: "No, really, just have a look at the definitions of Brit, Britain, British and so on."
B: "That's their pompous arrogance ..."
A: " Pompous arrogance without reason - long gone, dear B. - is bullshit of the highest order. - How nice, that we don't have to listen to them anymore droning on about their special role etc. etc. Continental bullshit-exchange will drop by several 'Farage' scales in the comming years ..."
