I Run On Caffeine Grease & Cuss Words T-Shirt

The I Run On Caffeine Grease & Cuss Words T-Shirt is built for the men who start early, run hard, fix what breaks, and keep moving with coffee in their system and grease on their hands.

The back graphic keeps it loud and straight to the point with bold distressed lettering that reads: “I Run On Caffeine, Grease, Loud Music & Cuss Words.” It is the kind of shop-floor humor every mechanic, welder, fabricator, truck guy, and blue-collar worker understands without needing it explained.

Finished with a small skull coffee mug icon on the left chest, this tee hits the right balance: clean from the front, loud from the back, and made for men who would rather be in the garage, on the jobsite, or behind a toolbox than sitting around pretending work gets done by talking.

Made for mechanics, welders, diesel guys, fabricators, shop workers, truck drivers, garage dads, and every working man powered by caffeine, bad language, and honest labor.

Material: Gildan 5000 Heavy Cotton Tee — 100% cotton
Print: Small left-chest skull coffee mug icon with a large distressed back print featuring bold stacked typography
Fit: Classic masculine fit — comfortable, structured, and made for everyday wear

Built for the men who run on caffeine, grease, loud music, and a few words that probably should not be said in front of customers.
