1. I totally walked in on Jackson whakka whakka whakking to some lesbian erotica. Man, he has a small one.
2. Roomie walks out with JBF hair.
Me: Whakka Whakka Whakka?
3. Jackson: Man, I couldnt sleep last night. He whakka whakka whakked it at four in the morning. I think they were trying to keep it down but its hard when theres only a wall between your head and their whakka whakka whakking.
