My boyfriend and I do a lot of weird things when we're being silly, like....pretending to be Macho Man and Hulk Hogan? (Hahahah it's embarrassing). So he calls me Macho Man Randy Savage and I always call him a "Little Hulkster."
Also, after a long, long, long inside joke about a movie, we ended up calling my parts "one-two" as in "to give 'im the ol' one-two." Hahaha.
