When someone is giving you head, you pull out right before you cum and you go all over their eyebrows. This makes their eyebrows white like an old man.
Smo loves having the Old Man's Eyebrows so much that constantly sucks guys off so he will always have them.

When a girl (or guy) is giving you a blowjob and you pull out of their mouth and go all over their eyebrows.
Cam gave his grandpa the old man's eyebrows, just after recieving the cucumber slumber.
