The most glorious day of the week where one excercises their pectoral muscles in order to get one of the sickest fucking pumps in the whole gym.
Person 1: Guess what day it is?
Person 2: CHEST DAY

Person 1: FUCK YEAH

Get the chest day mug.
Where a guy will send his chest even if he has no abs!
I was so happy when my boyfriend participated in Send Chest Day!
