Mt. Fuji 

Having such a massive bowel movement that it piles up until it reaches out of the water like an island that is made by an erupting volcano.

I ate way too much last night at the happy hour buffet and just Mt. Fuji'd the executive washroom.

Mt. Fuji Splugi 

Because the girl is so dry the male puts a spring water filled condom in the girl. Puts his finger in it and pops it. Releasing all the water in her makes it easy for pentetration. Before he bust he takes out and cums on top of her nipples, looking like the snow capped mountians of Mt. Fuji.

Hes wife was so dry and horny he gave her a Mt. Fuji Splugi and was the happiest man on earth.

It's snowing on Mt. Fuji

The only real and legit way of ending any haiku.

A) Sonic the Hedgehog,
You are the best game ever.

Mt Fuji 

"Too much", like a big pile of munchies you can't eat because it's too much... or just used instead of "too much"

Oh man, Mt Fuji ramen man, can't eat all that...

Mt. Fujied 

When going to the bathroom and crapping so much that it creates a wide and proud mound of poo that extends well above the water line, likened to the iconic image of Mt. Fuji dimly back-lit by the horizon and setting sun.

I Mt. Fujied it.
