Cophemeral

Mixture between the words confidant and ephemeral. A cophemeral is a fair weather friend. A friendship that is founded only on a temporary and/ or superficial basis.

Juanita thought her and her highschool friends would be friends forever, but it turned out most of them were just just cophemerals.

Cathemeral

A type of sleep cycle, related to diurnal and nocturnal. It refers to a creature that doesn't sleep JUST at night (like humans) or JUST during the day (like owls and bats), but instead naps at various times, both day AND night, throughout a 24 hour period.

Cats take cat naps because they are cathemeral.

College students often become cathemeral after excessive partying and late-night studying.
