Mack 

The most stupid person ever to exist. He sends dick picks to his mother at night. He has never felt the touch of a woman besides his mom. He is the person who hides in the group not telling anyone that he watches his mom on porn hub. He always wishes that he can fuck his mom.

Wow watching my moms porn you Mack.
