Get the half-great-great-great-auntmug. In the year of 2019 also known as the second year of the pre Ethan era (pee for short) the gang were playing some pubg. They threw sand clod at each other and Scott and Devin got into a fight about if an sand clod hit him or not. After two minutes define faggot ass left so zach, being a great person sent Devin a picture of a sand clod and a baby crying. Then Devin showing his great respect for life replied "you should seriously consider killing yourself." He then got back in the call 10 minutes later because he has no shame. Shout out to Devin and Zach to losing to opens btw.
