the type of weird, oddly sexual excitement gotten from something usually entirely non sexual. one can get a manus-boner from anything they're passionate about, but the original definition was weapons. traditionally a manus-boner was gotten only when looking at cross-sections of guns, listening to explosions, or gunshots, or watching swords being forged. however just like with the other kind of boner, everyone has their own tastes, and the definition was expanded to include the moment when good writing, an especially impressive freerunning manoeuvre, or even a piece of music makes you stop, and savour the moment creepily. now it can be used to describe just about anything that makes your one weird friend shudder with pleasure as if being edged except for anything actually sexual.

"dude. i was watching man of arms yesterday, and they made a chainsword from warhammer 40k. biggest manus-boner of my life"

*playing a videogame* "ooh, listen to the remmington r5 go. it's beautiful"
"yeah, the remmington gives him a manus-boner. just ignore him"
