In Act I Scene II, the following takes place:
Don Benedicto: Aha! and from whence hast this bough sprung?
Don Matheus: From the douche, no doubt!
Don Benedicto: The douche. The douche. Ye Gods man!
Tell me from whence hast the douche come ye can
Don Matheus: The douche is borne from yonder douche-bag.
Don Benedicto: Your humour does not humour me, sir. Begone or taste my steel.
Don Matheus: Thou steel be brittle, sir.
This pun is lost on most modern audiences, but in the play leads to Don Matheus and Don Benedicto fighting a duel (during the Edwardian period the word 'steel' would be pronounced very similarly to the word 'still', which then was used to refer to the way in which a mother holds her child. Don Matheus is implying that Don Benedicto's mother was incompetant. Indeed, he even goes as far as to suggest that Don Benedicto was dropped on his head at an early age, insulting both Don Benedicto's honour and intelligence).
'Douche' was a form of the old english word 'Douaché' meaning 'I sow'. It came to mean the seeds which farmers used to grow orchards (often apple orchards particularly). A douche-bag was a sack slung over one shoulder used to carry the 'douche' during sowing.
After this play, douche-bag eventually came to be associated with simpletons or fools (as it is the 'final straw' as it were of Don Matheus' ridicule which causes Don Benedicto to initiate a duel, which he eventually flees from - losing all face and honour as a gentleman).
This Elizabethan insult has in recent years resurfaced, particularly in the Americas, and has rapidly spread across the rest of the world thanks to recent innovations in communication technology.
Don Sampson: I think not sir!
Barney says your docuhebag
In other words a douchebag
Though the common douchebag thinks he is accepted by the people around him, most of his peers dislike him. He has an inflated sense of self-worth, compounded by a lack of social grace and self-awareness. He behaves inappropriately in public, yet is completely ignorant to how pathetic he appears to others.
He often talks about how cool, successful, and popular he is, yet never catches on to the fact that he comes across as a total loser. Nevertheless, he firmly believes that he is the smartest, most desirable, and most charming person in the room... and will try to bad-rep anyone who would threaten to expose this facade.
He fancies himself a ladies’ man, yet tends to be a joke to all but the most naive of women. He tries to portray himself as part of the in-crowd (a fashionista, an upwardly mobile professional, the life of the party, etc.) but only succeeds in his own mind.
To everyone else, he is an annoying and arrogant phony who comes across as a wannabe overcompensating for his insecurities. He tries to appear like the center of whatever group will tolerate him, but in reality, he is just a tag-along who mooches drinks, women, contacts, social standing, and other benefits from the group... while contributing nothing.
A-list ego; D-list status.
A douchebag will often bring his SLR to bars to take pictures of good looking girls (with or without their permission), perhaps pretending to be a professional photographer. He will try to be in as many photos as possible (often posing with his arms around total strangers or his friends’ girlfriends) and post them on his personal websites in an effort to convince his online community that he is a bigtime bar-star. He is also likely to boast about his "conquests" (usually exaggerated or fabricated), failing to realize that this only serves to impress fellow douchebags.
