If you were a beta as a child, you had to stay one until adulthood or else you'd disrupt the order. No one would let you pretend to be alpha. So when you saw an attractive woman in your community, you may have wanted to speak to her but you couldn't because that's an alpha thing to do and your tribe wouldn't like that. And if you FAIL, you're now the guy that tried to talk to that girl and she rejected you, which lowered your status even more. Maybe that's Grug's bitch, and if Grug found out what you were doing, he may kill you.
