Baby, will you please give me the Sexy Tiger like you did last week.
Horny people like to call their lovers sexy tigers. The image that comes to my mind is a buff, dark man with a nice ass. For men, I assume it would be a tall blonde woman with nice tits.
Or then again, maybe just the person you are currently initimate with.
"Oh, you are such a sexy tiger, let's do it right now!"
