When a
girl goes down on a guy, takes his
semen in her mouth and then comes up to him and spits it in his face. Much
like a llama spits at people in anger.
Judy was pissed off at
Bill for the rumors he started about her, so she took him into the back room of a party, sucked him off and then spit it in his face right in the middle of the living room in
front of
everyone. Everyone knew she was 'The Llama.'
