slackidasical

When a person is slow moving and uninterested; characteristic of a student who doesn't want to complete an assignment, homework, whatever.

My student was slackidasical about the science project but surprised he earned failing grade.

sackstache

Testicular hair. Often a source of pride for Millennials unable to achieve a proper ironic mustache.

Hipster A: Bro, how are we supposed to get into this uber-popular "unknown" brunch establishment with that pathetic looking peach-fuzz on your upper lip?
Hipster B: No problem, my dark-skinned-friend, I am going to flash the hostess this mad sackstache I've been cultivating. She's going to be super impressed and we'll be sipping mimosas well into the evening.

slackfired

When you do something half-assed and end up making it harder then it would've been if you had just done it the right way to begin with.

Well, mopping the floor without vacuuming up the dog hair first really slackfired.

slackfire

To unintentionally make achieving a goal more difficult by trying to achieve it the fastest, easiest, cheapest way possible.

My plan to save money by not doing routine maintenance on my car slackfired when the engine blew.
