A Fantasmagasm happens when something is really, really awesome. Not necessarily sexual. It consists of an immediate smile and jumping up and down in giddy fashion going "Omg! That's so awesome!" or something to that effect. It is pure happiness and excitement.
a combination of fantastic , majestic,incredible and fabulous. Used to describe items or events that are so shitastically amazing that they cause ones balls to explode due to joy overload.
Man, weekend at bernies was on last night, that movie is fucking fantasmacredilous, i was cleaning my ball off the walls for hours.
yes its possible...it's even better than fantasmagorical.
It's really really really really really really really really epic and amazing and is to only be used in rare occations.
