Not to be confused with

BaggiesBecause of the name "phat pants" some people who are not involved in the rave scene mistakenly confuse phat pants with baggy pants. Baggy jeans or "baggies" are a specific type of cut with wide legs, the same width all the way down the leg. They are closely related to loose fit and are sometimes incorrectly labelled as such.
FlaresFlares are another cut of jeans involving wider legs. The distinguishing feature of flares is that they are a normal fit from the hips to the knees and then widen out from the knees down to the feet.
Hammer PantsHammer Pants are sometimes confused with Phat Pants, but are actually very different cut. Whilst Phat Pants usually have a fairly high groin and taper out from the waist. Hammer Pants had a very low sitting groin and very wide hips, whilst tapering in towards the ankles.
Bondage/Tripp Pants Bondage pants (also known as Tripp pants for the most popular brand of bondage pants), which are similar in bagginess to Phat Pants, but generally have darker color. (Usually black or grey) Furthermore, bondage pants tend to have chains, buckles, rings, straps, and other similar items on them, giving them somewhat of a 'BDSM' look, whereas Phat Pants usually don't.
