Onyomi

SEI, JOU

They SAY that when JOE Stalin first prospered, his dish was finally able to become full with heaps of food.

( を ) も＊る	a heaping bowl of food / a raging fire / something overflowing with solids (but not liquids - that's a different kanji with the same pronunciation! 漏る！！！） ★★★☆☆
さか＊ん ( な )	robust, active, overflowing with something-or-other : A flurry of applause, a fire vigorous enough to roast an ox, a flowering of culture. ★★★☆☆

盛り上がる(もりあがる)

to liven up ★★☆☆☆
盛 (heaps of!) + 上 (above) = 盛り上がる (to liven up)

盛りマン(もりまん)

bulging pudenda ★☆☆☆☆ CCW ABU
盛 (heaps of!) + マ () = 盛りマン (bulging pudenda)

a bulging pudenda. Not like an average camel-toe. More like a set of labia that is thrusting out of a pair of tight pants like a she-boner.

Seriously, there's enough guys that are into this that they had to make up a word. Seems kind of a homo-erotic fetish to me.

But on the other hand, who says only guys should get to brag about the size of their units?
