clothes that athletes wear under their jerseys to "keep warm"...costs a shitload

Lightweight performance apparel popularized in the breakdown by Big E and his iron pumping friends, including JT the rookie and Coach. They participate in a supervised after-hours tackling club in a warehouse, and do not appreciate Cheese stopping by in a Cotton XXL shirt. They started this thing and are just trying to prevent everyone from bringing them down.
The house is paramount

Clothes that rednecks who think they're all star baseball players who get all the girls. Football players use to wear it underneath their jerseys and pads. Most baseball players who ride the bench wear it.

Under Armour sports apparel that is inappropriately worn during public, non-sporting events (eg: bars, parties, classroom, restaurants, etc) in an attempt to pass it off as fashionable.

An Under Armour Mom is a woman between the age of 25 and 50 (there have been sightings of UAM's up to 65 years old, however) who has children, is currently married or divorced, and thinks she is an athlete. She attends yoga class every now and then, she might even go for a quick jog with her baby in the stroller, or participate in a triathlon "for the challenge" (rides a mountain bike with aero bars, doesn't really know how to swim). Due to her active and healthy lifestyle which makes her better than everyone else, she requires that her clothing express her passion for moderate exercise to her peers. She will regularly spend hundreds of dollars on Under Armour clothing and wears it on a regular basis even when not "training". T-Shirts that say "ATHLETE" on them, or "TRAIN HARD" or "PROTECT THIS HOUSE" are slogans of choice. When it's cold outside, she needs some "Coldgear". When it's hot outside, she seems some "Heatgear". The performance enhancing microfibers help her perform better, whether it be kicking the soccer ball around with her family, or picking up a pizza in her gigantic SUV.

She is a poser.
