Red Lipstick
When a male dog's penis unsheathes, it resembles the action of someone twisting red lipstick, also because a dog's penis is red.
Dude #1: Your dog totally unsheathed on me when I pet him!
Dude #2: Well, he wanted to give you his red lipstick!
Dude #2: Well, he wanted to give you his red lipstick!
