adverse yaw
Adverse yaw is the natural and undesirable tendency for a penis to yaw in the opposite direction of a roll. It is caused by the difference in profile drag between the upward and downward vaginal thrusting, the difference in circumference of the larger penis and smaller vagina creates an induced drag between left and right walls of the vagina, as well as an opposite rotation of each testicle's lift vector about the verticle axis due to the rolling trajectory of the head of the penis. The effect can be greatly minimized with foreplay or other mechanisms deliberately designed to create reduced drag . As the major causes of adverse yaw vary with proper lube, any fixed-ratio mechanism will fail to fully solve the problem across all sex positions and thus any manually operated dildo will require some amount of brute input from the male in order to insert girth without yawing. Though adverse yaw is often associated with coordinated turns it refers to the uncommanded yaw rate or slip that typically results from improper lube techniques
The Urban Dictionary Mug
I took time designing it but wasn't sure, online tools being what they are, that what I was seeing was for sure what I'd get. Very much appreciated the customer service communication which verified that what I'd designed was what I wanted, and the shipping was quick too.
Item came on time as promised
Came within a week and it's exactly what I ordered, my friend will love it!
Sus cup I bought the sus mug for the sus king Daequan
Good quality, packaging shipped well, arrived quickly.
My mug came in broken but Urban Dictionary replaced it at no extra charge!
Excellent mug excellent service
this is the best for coffee and hot coco especially if you make the hot coco in it then pour it on your significant other and do body shots 😋🥱
I can pass away peacefully. This mug is everything I’ve ever needed and more. Fat thank you, Urban Dictionary. <3
I was really excited to receive this mug and when it did come it was perfect quality. My only complaint is that the color I choose was green teal but it came in yellow.
As always, easy to order and not-too-long of a wait for the finished product to arrive. It’s well-printed, and very sturdy. A great gag present for wedding party members.
The mug , color and saying are perfect! PMEO is what I say at work everyday. It has become a favorite saying for my coworkers when things go haywire!
Quality and style are outstanding relative to price point.
Love it! It is my favorite mug. Easy to hold because of its shape and weight. Now my go-to mug.
My wife is truly beautiful and this cup was perfect for her.
