HE's such a despicable villain, he spit in 4 of my rice fields!!
foul, trifling,low, despicable - not used trivially. Used about child molesters and such.. Often used like this: 'XXXに いやしい',where XXX is the thing he's a dick about.
contemptable, despicable (literally, "ought to be despised.")
to despise someone. This is where it gets tricky. Only a bully or a dick いやしめるs someone.i.e. "Ha ha your parents got divorced!" or something. I guess you could say, "Don't いやしめる or you will become いやしい."
not just a coward ,but someone who does treacherous, trifling bullshit because they're a coward - like if they fight you they know they can't win fairly so they'll knee your groin, they're a 卑怯なmotherfucker.
put yourself down
to put yourself down (BOOBOO: only used when talking to others - mumbling "I suck!" to yourself doesn't count for some reason)
The SUN ascends every DAY,
but the MOOCOW'S dialect is hard to say.
the VILLAIN is , of course, despicable.
