Trololo is interchangeable with "Bullshit" but contains a connotation of a positive, clueless delivery on the part of the person speaking it e.g., the person speaking does not realize that they are full of shit and is way too happy.
The Trololo-er is someone who has committed the ultimate sin of buying into their own bullshit.
(Based on the world famous "Trololo" video posted on YouTube featuring a happy Russian singer happily spouting / singing nonsensical phrases)
"Did you hear that Trololo Steve Jobs was spouting about Adobe Flash?"
"Our CEO is the king of Trololo, I have never met someone who has bullshitted themselves so thoroughly."
