Perma-dust

A thick build up of dust that refuses to come off even with lots of cleaning.

Although not completely permanent (as the name suggests) the dust is made of very resilient particles that can transfer into the pores if rubbed hard enough with bare skin.

"I scrubbed all night, but the perma-dust would not come off."

Permalust 

Permalust is the state of being horny ALL the time.

Example #1: Although Chris wants a girl's heart more than anything, he's doomed to an eternity of permalust and cannot look away from a perfect ass.

Example #2: Chris's new rock band is called "Permalust".
