The usual look of a male who is well-practised in the act of self guzzling of urine. Can also occur when the male has induldged in the gulping of another man/woman/guinea pigs yellow release. It is also necessary and useful to start with a white beard, as dark tinges tend not to show the yellow twinge that makes this effect so thrilling in shady arenas.
Daddy daddy, why is your beard so yellow?
I spent all evening near the downpipe of the urinals, so now I'm feeling spritely and want you to call me papa yellow beard.
