look up any word, like the eiffel tower:
So terrible, beyond bad that it can only be described as garbage-like.

Terrible, useless, unfathomably bad, ridiculously horrible, sickeningly awful

Shaday's personality in combination with her garbageous looks made her completely unappealing to everyone she met.

Reminiscent of the style of the rock band Garbage.
Yesterday I discovered this fabulous garbageous band, Dollshead.
