And I think only now did it sink in that your username is not “WOOK-IN-A-PUB”. Which I took to some kind of reference to the Star Wars cantina scene.

The color of my hair. It’s passed grey and moved into all white.
I blame you for… er… you. Your username came from that Buckwheat thing, right? And he’s a dude, so…
You betcha!No worries though; it happens a lot.
Me. Exactly. Except I’m 50.

My hair…I have the sort of strawberry blonde color that women tell me they wish they had.
But they’re not fooling me…I know it’s just code for their attraction to my frighteningly enormous penis.

And I once won a “sexiest bald head contest” at a bar I was hanging out at.

When women find out how many kids I have, or how old I am, the comment on my relatively youthful appearance.
Otherwise, the comments are few and far between, and generally relate to my fitness (arms, body fat, etc.) or that my head is well shaped so I could shave my head.
Shakes, when you are walking away and you overhear people mutter, “What an ass,” it may not be a compliment!

While living in Mexico as a teenager I got a lot of “you’re so pretty” random complements, but nothing specific singled out. Since leaving Mexico to go to college (at age 20), no man has complemented me on any physical characteristic whatsoever, except for one instance of “you’re nice and tall” from a very tall guy: does that count?
(What changed, I think: I’m tremendously antisocial. In Mexico I’d meet people when hanging out with Mom, who’s very social; in the US I only meet people through school/work, where personal complements are less appropriate. I do get mad props for my leet mouse surgery skillz on a regular basis.)
Women (particularly grandmotherly types) like my hair (it makes cute sausage curls when so inclined).

Women often talk about my hair or how they hate me because my eyelashes are so dark they look like i’m wearing mascara even though I never am.

breasts.
the only person who ever compliments me is my husband, and that is definitely the one I hear the most.
I’d like to think the only reason I don’t get compliments from others is because they accurately pick up my vibe that it would only make me uncomfortable and otherwise they would be constantly bringing up my beautiful big blue eyes. That’s what I compliment myself on most.

Men first note my hair (though women do too) because red is eye-catching, and then how fair-skinned I am. I think “ungodly pale” but they say thing like “milky” which sounds nicer. Some men talk to my breasts, but I don’t think they mind.

Most often heard public praise: Hands and voice. My SO routinely goes to town on how amazingly delicious my mouth/lips are and how squishable I am. The squishable part is kind of weird, since I only weigh 140lbs, but my skin is pretty flexible. To each their own. Who am I to complain or tell her she is nuts?

Guys usually compliment me on my boobs (they’re relatively large for my frame - I’m a size 2 in clothes but a C cup) or my feet and ankles (in the summer). Girls mostly will comment on my skin.
