Slackback 

A slackback is referring to a day when you are slacking off from dialing and selling. It can also mean a day that you did not post any new sales on Slack.

Becky "I just got a chargeback."
Mandy "Girl, I hear you, but you have seen your slackbacks? Get rid of those days and the chargeback will disappear."

Sharkjacking 

An extreme sport of which the object is to masturbate a shark, the greatest achievement possible being an ejaculation by a Great White Shark. One participant ties raw meat onto his/her ankles and swims near the shore to lure in the animal where three others wait. When the shark approaches, the three sleepers wrestle the shark into submission and the "baiter" manually stimulates the shark. Upon ejaculation it is important that the team clears the area as quickly as possible because post-orgasm behavior of sharks is often erratic and the chance of participant injury is increased due to close proximity.

This sport can be played by a team of more than four, but traditional Sharkjacking is done with a team of four.

"Nothing like a game of Sharkjacking in the morning to get the blood flowing, eh boys?" --Chris Kahn of the Starship Enterprise
