Google doesn’t pay attention to whether or not there’s a period even when you search a term with quotes.

Love letters…”
Buck Naked, Texas Ranger.
Rev. Buck Naked was a leading figure within the Church of the SubGenius from the 80s and 90s.
Gen. Butt Naked was a former Liberian warlord turned preacher from the 90s and 00s.
“Abu Naked” were a house of Druze sheikhs in the mid-19th Century (I have no idea why I came to know this and why I still recall it).
I think I’d have a better time in the company of Buck Naked.
Buck Naked is the person, butt naked is a condition. Buck Naked was buck naked in the 7-11 last night.
I admire someone who has the courage to ignore bad advice, even when it comes from himself/herself. 
of the options butt naked

What? No mention of Buck Naked and the Bare Bottom Boys?
Buck. “Butt” is too specific.
