Saying derived from youtube channel MrGoodBoody. For females it means simply to 'not to be skinny' to the point where no bones are showing.

For males it means the same, and also to use protection.
"Bro, you look sucked the fuck up! Get some muscle and cover yur bones!"

"Dang that girl has absolutely no curves, she needs to cover her bones."
