Top Bunk 

The act where a male assumes the top position during the sexual act of 69ing, opposed to the usual bottom position where the female is on top. This can be also referred to as “calling top bunk”, and “top bunking” if used as a verb.

She wanted to 69, but she is bigger than me and would crush my face, so I called top bunk.
