throw a monkey wrench in the works
throw a wrench in the gears

vacuum up
bust a cap in someone's ass
slob
gum up the works
gob off
moon
know the difference between one's ass and one's elbow
know one's head from one's ass
know one's ass from one's elbow
know one's head from a hole in the ground
splatter
hang up one's fiddle
put in one's oar
assplant
put in an oar
put one's oar in
bust one's gut
beat the tar out of
throw a monkey wrench into the works
