First off, how amazing is this photo?
At first I thought it would be fun to find the origin of the phrase “burst my bubble” but it’s not readily available in the fifteen minutes I’ve allotted for this post. Plus, the stuff I found on a random search was SO much better. Since I can’t find the photographer to give him or her some credit, I submit this answer to the question “What does the phrase ‘burst my bubble’ mean?” The answer was given by General Smashingtor on yahoo answers. Thank you, General.
So much soap spilled over the soil of earth, and finally when the last bubble floated above the puddles of his comrades and enemies, he just though…. I won… I WON!
Then some random human came up and popped him, completely destroying him and ruining any good feelings he had, because he was now dead.
So when you burst someone’s bubble, you ruin their fun, or something similar. You ruin/stop/impede on something they are doing that is fun, exciting, or you could even be correcting them.
BUT DON’T FORGET THE HISTORY!
