O-Turn 

Two consecutive U-turns or a 360 degree turn.

You're driving and think that you're going the wrong way so you do a u-turn, as you are doing the u-turn, you realize that you were actually going the correct way in the first place and so you do another u-turn, hence you have done an o-turn.

O-Turn 

When one sexual partner is about to reach climax before the other, and is strongly encouraged to turn back from his or her orgasm, and wait for the other partner to reach a similar level of arousal.

No! Pull an o-turn! I'm nowhere close!

2 o'clock turn 

The 2 o'clock turn is an event that happens every day at 2 during the work week to avoid the midday slump. It's a time for you and your coworkers to take a break and do something funny, relaxing, or to wake up for the rest of the day. Basically take a break to recharge your brain! At Brewer's Lantern we like to take shots of Red Bull and go live on instagram or post stories and challenge others to turn as well!

We need to do the 2 o'clock turn before I fall asleep
Get the Red Bull ready... it's time for the 2 o'clock turn
