In my language, the word awkward translates "uglovatiy", literally means "angular". Just like the word implies - your actions are NOT "flowing". Clever, huh? In Russian this word has even a worse connotation.
There were a few times up until a year ago or so, that even my mom would notice me being "awkward" in some social situations, and she was like, never be like this again please, it looks very unappealing, as if you stole something, or as if you are trying to cover up something. She's very good as spotting such things. We were on a family vacation, and me and her were walking to our hotel, and this guy walked behind us, then walked faster, and she caught a glimpse of his face as he walked by us. Shifty eyes, stiff/fast walking. She's like "wow, he's so awkward and creepy... it's good that you're walking with me right now, I got scared".
She's in her forties, but she thinks more like a younger person. So yes, being awkward is a REPELLING quality, women get almost scared by it
