look up any word, like bukkake:
When girls with droopy tits are getting it doggy style, their tits hang and have a cylinder-like tube sock shape. The circumference of the base of the tit in this case is like 1/5 the length of the droopy tits and is very gross. The width of the tit collapses due to gravity and it just spills out and continues in length.
"Every time I see a fat chick, I just know they have tube sock tits! So I decided make sure, and during doggy style I saw those droopy tube sock tits"
