Tube boobs= tube socks with a soap bar dropped in them. Very long saggy boobs. Ex: little boy goes to sit on grandma's lap " get up Johnny I need to adjust myself you're hurting me" Boy gets up you see grandma pick her boobs off her lap... "Ok Johnny you can sit up here now"
Lol trust me i've seen enough. And basiclly any very large boobed woman will most likely have them once they get older. Unless… they work out
