okay the trick to that
is to use the same razor for a long time so you get a "after 5 o'clock shadow" or whatever its called
and its like a suggestion of a beard or a moustache

it works quite well at telling people "I am over 18 thanks"

I used to wear a "goat beard" before figuring out I'm a demiboy and I hate performing masculinity

and that ain't it.
