The term 'zwtf' is used when an inflationary use of the term wtf characterizes one's language use in chatrooms and/or emails resulting in a devaluation of the original wtf.
When it then comes to situations which seem really wtf you need to find a term stating the actual urgency and significance of the 'wtf-situation'.
For such cases the letter 'Z' puts much more emphasis on your exclamation of wtf.
Dude1: Hey there is another 'kill the kitten game' on newgrounds!

Dude1: And I learned in school that Hitler was a bad guy.
Dude2: WTF?
Dude1: ...
Dude1: Your mom just killed Chuck Norris and Mr. T simultaneously.
Dude2: ZWTF?
I don't buy the schmegegge about Morty sleeping with Moira.

Looking or experiencing something nice after witnessing something horrid like a disgusting gif or a disturbing video. Typically used as eye bleach are nice images of whatever makes the disturbed person happy.
Noun. Portmanteau of "street" and "road": it describes a street, er, road, built for high speed, but with multiple access points. Excessive width is a common feature. A common feature in suburbia, especially along commercial strips. Unsafe at any speed, their extreme width and straightness paradoxically induces speeding. Somewhat more neutral than synonymous traffic sewer.
Did you see what the traffic engineers want to do to our street? They're going to turn it into a total stroad!
