Spewing out a random combination of words or facts with no intellectual input at all does not make you funny, or clever. Now, I know I'm not someone to judge anyone's sense of humor. It takes no thought to it, and just saying "PIE!!!! PIZZA HUT IS AWESOME XXDDD! GIRAFFE BOO! X3" Is not humorous. It takes literally no intelligence to spout up gibberish, which is why this appeals mostly to children. You know, they're neither fully developed or have much experience of the world. It just melts everyone's brain within a 5 mile radius.
The latest buzzword used among mindless teenagers as a way of showing just so utterly irreverent their predictable sense of humor is. Particularly dominant among English teens and University students, the word "random" or the act of being "random" is a desperate plea for others to recognize how totally against the grain of the norm you are and that you're really crazy and out there. Trouble is, being "random" is predictable, boring, moronic and extremely sad indeed.
If you want to come on here and say that you're random, you have the creativity of a brick.
