Senior slack

The general state of laziness experienced by seniors in high school. It often occurs near the end of the school year when their remaining time is essentially pointless, as many have already been accepted into colleges/universities. It is accompanied by a lack of studying, caring, or effort.
Junior: Aren't you going to study for your calculus test tomorrow?

Me: Nah, senior slack has hit me hard. You'll get the feeling next year...

slack water

Water that originates in the upper region of a pair of slacks and which then flows down to the cuffs, the socks, the shoes, and eventually pooling on the floor or patio. Although it is not well understood what triggers this flow it is widely surmised that anxiety, too much liquid intake, too small of bladder capacity, or lack of accessible toilet facilities may contribute to this startling 'wonder of nature'.

The makers of the personal hygiene product Depend® Fitted Maximum Protection Briefs for Men approve of this definition.
I've heard that it was slack water on her uncle's veranda in Venezuela along the Orinoco that inspired Enya.

slack karen

Slack Karen’s are the busybodies at your office who treat it as their own social media fiefdom. They monitor all channels, insert themselves into any discussion, and argue with you if you post something they disagree with. Most of their work day is spent in arguments and self-started drama

They are usually very liberal but conservative versions exist too. If you call them out on their odious behavior, they’ll DARVO and pretend to leave forever, only for the cycle to restart the next day.

Person 2: They are upset about everything; they are a Slack Karen. Do not engage with them.
