Flex Paste

The paste version of the blessing from the god Phil Swift, known as Flex Seal. Inspired by Flex Tape, the Flex Paste commercial references the “NOW THAT’S A LOTTA DAMAGE” meme and the “I SAWED THIS BOAT IN HALF” meme, showing that the gods above have given this as a gift.

Flex Boy

A skinny boy who works out constantly but doesn't get results, so he begins to flex 24/7 in order to appear buff and muscular. Flex Boys usually think they are very handsome and have a tendency to look at themselves in the mirror whenever they have the chance. Never become a flex boy, try to get results through working hard instead.

- "Oh my god, why is Cristobal flexing all the time?"
- " He must be a Flex Boy."
