Bathroom Time Off - Similar to PTO (Personal Time Off), one can easily achieve 40 hours of additional vacation time by taking a daily 9.23 minute dump at work. Executive types and employees with seniority can often increase their BTO up to 60 hours/year by extending their bathroom sessions out to 13.85 minutes.

Damn! I've got to level 168 on Candy Crush this year just on BTO alone.

I took so much BTO this morning that my legs went numb!

Thank god the company WiFi reaches the bathroom or I would've use $30 bucks in data while taking BTO this week.
