"I was thoroughly caught off guard by the recent gaysplosion"
Gaysplosions are a naturally occurring phenomnon that occurrs around internet forums whenever the words 'Gay Rights' are used in a sentence.
They occur like crop circles and are naturally populated by large groups of people wearing big floppy clown shoes and debating about shit they have no idea about.
Ellen posted on my web forum and started a gaysplosion. All these douche bags started talking about genetics and shit and began wearing clown shoes. It was shit yo.
