Strict vegetarian 

A vegetarian who avoids consuming all animal products (eg. meat, fish, eggs, dairy, gelatine etc.) However they still may wear clothing or use other items which involve animals (eg. leather shoes etc). This is essentially a vegan diet, but does not take the vegan philosophy of avoiding all animal products.

person 1: She is a strict vegetarian?
person 2: Correct, she doesn't eat any animals products.
person 1: Oh, thanks for clarifying that for me.

Semi-vegetarian 

Someone who tends to eschew animal flesh, especially consumption of red or fatty meats, but still will occasionally eat meat, unlike a vegetarian.

Whereas a vegan may confine his diet to fruits and vegetables, a semi-vegetarian might eat fish weekly; eggs, honey, and dairy products frequently; and beef, lamb, or chicken an average of two days each month.

Socially Vegetarian 

To be socially vegetarian is when you follow a predominantly vegan diet, but are prepared to eat some egg and/or dairy when dining out with friends to not make things difficult with regards to restaurant selection, etc.

Joe: Guys, let's go eat at the steakhouse.
Dave: Fuck, we can't though. Jimmy's a vegan.
Steve: They do a mac n' cheese. That's vegan, right?
Jimmy: It's not, but it's fine. I'm socially vegetarian. We can eat there.

...everyone's happy!
