If Top = King, and Bottom = Queen: what does side equal?

Quite remarkably just had someone try to chat me up and in the process he made a clunky attempt at humour saying tops are kings and bottoms are queens, I guess in a roundabout way to politely ask me ‘the question’…my brain kind of shut down from overheating due to the surprise of being come on to and the way it was done, so he’s gone and I’ve missed my chance. Has got me thinking what a side is in that scenario though
