Stretchy Pants is a Christmas song by Carrie Underwood released in November 2021.
The song is a humorous take on Christmas dinners, as the singer has found a way to avoid being overstuffed: not only has she not eaten all day, but she has also chosen to wear pants made of Spandex and/or Lycra with an elastic waistband. This will allow her to gorge on dinner without feeling the tightness which regular clothes would cause. At the end of the song, not only has she had three rounds of dinner, but she brags that she still has room for more and comments "Santa ain't got nothing on me".
