Batwings 

When one's scrotum sticks to the inner thighs due to sweating in the groin area. This situation can be nicknamed 'Batwings' because the image created by this scenario can resemble a bat and its wings. The shaft of the penis can be see as the body and the stretched scrotum to either side can be seen as the wings. Many males (and hermaphrodites) find this common occasion displeasing.

Batman: It sure is hot in this cave.
Robin: Yeah I know, I'm beginning to have batwings.
Batman: That was very unnecessary.

Buttwings 

Buttwings are small wings that can be found on the rear-end (butt) of something; they are generally found on non-existent things like Victini and anything that's free to buy.

Victini has a pretty prominent, but small pair of Buttwings that allow it to fly around and cheat the laws of physics.

Buttings 

When a girl is too large for her leggins and the fabric stretches to such a degree that you can see her butt crack. Important to note that the girl is not wearing a shirt or skirt to cover said leggings.

That girl has got to lose those buttings. I can totally see her crack.
