Thumb Day 

When someone goes to the gym and spends 90% of the time on their phones scrolling through social media

Looks like its thumb day again for Jimmy with his usual routing... 3 sets of 5 snapchat selfies and 10 sets of scrolling through facebook until exhaustion

Thump Day 

Wednesday is hump day. Thursday is hump day ^ Tth power. We bring the noise on Thump Day.

AKA party it up, get stupid, get your drink on. Thursday is the beginning on the weekend.

We're gonna party it up with a 4 day weekend starting on Thump Day.

Thumbs Day 

When all of your friends are talking about if they’re going to do a legs day or a chest day at the gym, and you tell them you’re just going to play Xbox all day.

Nah I’m not going to the gym, it’s a thumbs day for me. I’ve been light on cardio also so I might walk to the microwave soon.
