Somebody who abstains from consuming products derived from the exploitation of animal life.
When asked why she was vegan and abstained from drinking milk, Mary explained that cows are severely confined, artificially inseminated and shot up with numerous hormones in order to produce milk on commercial dairy farms - something she wished not to contribute to.
Somebody who abstains from contributing to the economy and salvages society's wasted food and resources rather than purchase more themselves. Often pertains to a VEGAN (somebody who doesn't eat/wear animal products) who only makes exceptions when dealing with otherwise wasted items.
Tom taught me that as a freegan, he would much rather grab bagels out of the dumpster of a bakery instead of purchasing them himself, because he thinks it's a shame how much perfectly good bread places like that waste everyday.
