Market Vegetarian 

A person who does not buy meat (from either restaurants or grocery stores) but will eat meat if it has already been prepared.

The inclusion of market refers to the fact that this person's buying behaviour (from the market's perspective) is like a vegetarian.

At a house party:
Person 1: Did you just have a meat pie? I thought you didn't want to have meat at the restaurant last week?

Person 2: I don't buy meat, but if it's already been purchased I'm ok with having it.

Person 1: Oh! So you're like a Market Vegetarian?

Person 2: Exactly

Person 1: What a hipster

You act and tell everyone you’re a vegetarian, but eat prime meat cuts at social gatherings because that shit is too good to pass up.

Just so y’all know, I’m a Bostonian vegetarian, but these pork ribs hit tho and I can’t resist

Weekday Vegetarian 

An approach to adopting a more plant-based (flexitarian, semitarian, demitarian, reducetarian) diet. Involves restriction of meat/seafood consumption to the weekends and only eating vegetarian-permissible foods the 5 weekdays of every week. Additionally, weekday vegetarians sometimes endorse/promote using seafood consumption to cut down meat-consumption (especially red meat consumption) on the days meat is eaten.

Is often (but not always) used as a tool to slowly transition to a fully vegan, vegetarian or pescetarian diet pattern.

“My son kept failing or quitting the vegetarian diet because he felt too restricted and overwhelmed. He now does the Weekday Vegetarian diet to limit his intake of animal products and is maintaining it a lot more easily.
