Theres only one commonly known symptom of boytardation and thats not being able to get a boyfriend. Boytarded is only used if you are exceptionally good looking. If you're ugly then being boytarded is not an excuse as to why you have no boyfriend.
Girl, i think i'm boytarded. I mean, why can't i get a man who can give me what i want?
First Person:I think I'm boy retarded.
Second Person: No, you're just ugly.
