An internet meme which gained popularity in early 2010. Often described as the "Russian Rickroll", the video features a very happy and well dressed Russian business man singing a variety of sounds in different pitches (La la la la la, la la la, la la la, ho ho ho ho ho). The title of the video is "Я очень рад, ведь я, наконец, возвращаюсь домой" which when roughly translated means "I am very glad, because I'm finally back home".
Jim said something really funny, so I laughed at him like that Russian did in the Trololo video.
A video posted to youtube, which features a Russian man in a suit with a huge grin singing nonsense like "trolololololo, tralalalalala, yeyeyeyeyeye". The song is called "I'm so happy I'm finally coming home" and had real lyrics until Soviet censors denied them and the singer changed them to nonsense. The video itself is a recording of a 1966 performance of the song.
Trololo, tralalala, hahahaha, yeyeyeye!
"Trololo" is any bullshit (or other) speech which is completely unfounded in reality, contains absolutely no truthful substance but is spoken in a happy, optimistic way. Generally, the speaker is not aware that they are completely full of shit - this is most common amongst clueless businessmen or entrepreneurs pitching venture capitalists on lame business ideas.
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)
"That presentation was the worst bunch of Trololo I ever heard."
"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."
