Most of these are appearance-things, not behaviour.
I've been told by guys that my mannerisms come across as cute, but while I'm not sure how much of that is true or what specific things I do that they like I can give a brief rundown of personality traits that I think they might be referring to.
I'm a soft-spoken, timid and shy introvert (though I definitely don't believe that that's cute behaviour. It can just as easily be seen as "socially awkward nerd" or come across as autistic. It can also sometimes make me seem cold and distanced towards people I don't know, which is a very unflattering characteristic that I'm trying to work on.)
I'm a total softy to a point where I don't even like hurting insects. I usually catch them and put them outside.
I'm pretty over-emotional and sensitive (I know, red flag) and get excited (and conversely cry) really easily
I'm really emotive and it's super easy to tell my mood from the way I look
I'm a total pushover
Personally I think, as some anons said, when people, especially people like the ones probably browsing cuteboys, say someone is 'cute,' what they mean is sort of feminine or maybe even just boyish mannerisms, submissive personality types and maybe a kinda demure disposition.
