Boxers: Baggy short-like underpants worn by me who claim they need "more space". In reality they just don't want to be caught dead in tighty whities which are the rivals of boxers. Boxers tend to have prints/patterns/cartoon characters on them. Many men who wear boxers wear them above the jean as to sag and display their proud patterns. Women find boxers as an absolute turn-on as they seem them as the grown-up men's underwear choice. Obviously women love when men wear such grown-up patterns as Spongebob or Corona on there underpants. It only makes sense (roll eyes). . Boxer-Briefs: Boxer Briefs have the length of boxer shorts but are made with the same material as briefs. These cotton boxer shorts are usually worn by the athletic male types and men who claim they need room and support for their package. Women are split on their feelings toward boxer-briefs. In some camps, women love them...in other camps...women find them the same as tighty whities. . Briefs/Tighty whities: Briefs or tighty whities are short speedo-like underwear that are generally white and worn by men who claim they need support for their large packages. These men (whether they are lying about their packages or not) are taking a huge risk when wearing these tight pairs of underwear. Many women are turned off by their child-like design and display of the male thigh. White pairs of briefs are often called "tighty whities" due to their tightness and whiteness. Even though briefs are made in a variety of colors, they are still often called tighty whities by women who apparently have no clue how to differentiate colors. Thong: Google it.

That pretty much summed it up. It used to just be two choices for guys boxers or tighty whities until more recently boxer briefs came out and thongs lol those are girls underwear.

Well he defined the first 3. There are also a style a few other styles like... Trunks: which are between the length of boxerbriefs and briefs. If you were to hold them up, there pretty much stright across on the bottom. The leg area is pretty much the same length as the bottom of the crotch section. These are great because they don't bunch up when you put on a pair of pants, and they don't have that bad apearance that briefs have. Bikini style: these are the same as briefs, but have less material on the front leg section. But then have the same coverage in the back. String bikini: same as bikini, but now there's a string on the side instead of material, then it acts the same as bikini in the back. Jockstrap: same as string bikini but in the back, there's no material except the elastic bands. People who do sports tend to wear these for support in the front, and more air in the back. Thong: has a string that goes down the middle of your butt, with about 1 inch of material around the waist. Guys wear these for great support in the front, without having to worry about underwear lines. G-string: same as thong except waistband is just a string.
