Snortingly-sarcastic term for a shyster's/villain's huffily acting like he's a conscientious peaceable virtuous caring-about-fellow-humans person who shouldn't be suspected or criticized, when of course in reality he's just a self-centered a**h**e who's totally undeserving of any praise or respect.
A prime example of someone's deciding to use this shameless tactic would be in "The Untouchables" with Kevin Costner --- when Elliot Ness angrily confronts Al Capone on the stairway and accuses him of murdering people and otherwise being a horrid crook, Capone indignantly lashes out right back at Ness for his "talking that way in front of Capone's son"... Ness's feelings would therefore be something like, Capone decided to go all "family man" on me --- how infuriatingly disgusting!

Take the virginity of a Trekie (usually a female).

The phrase is of unknown origin but it seems that it comes from the "franchise" of Star Trek porn parodies such as "Sex Trek: the next penetration" and "Where no man has cum before".
Fred: Hey, you know what? I slept with Janice last night!

Bob: No! Janice the Trekie?

Fred: Yeah..

Bob: That's what I call "To boldly go where no man has gone before"!

'Going to see a man about a dog' is an often used a euphemism in Great Britain. It is most often used when telling someone you are going to the toilet. It has also been used to describe meeting a woman for sex i.e - when you replace the 'man' and 'dog' in the sentence with their opposites 'woman' and 'cat' (but in this case we use another word meaning cat, 'pussy') so you end up with 'going to see a woman about a pussy.'
'Where you off too?' 'Going to see a man about a dog.'

'Where you rushing off too so fast?' *Man Winks* 'Going to see a man about a dog'
