baby pool 

When a male cums, and it lands in the belly button of the lady,or fellow dude for all you man on man lovers ;) The sperm are the "baby" of this phrase, and the belly button is the "pool"

---Look honey! I made a baby pool!!!!!

---Ugh, get me a towell, need to get rid of the baby pool...

drowning in the baby pool

To spend time wallowing in misery over trivial, materialistic, and superficial matters. The baby pool is never deep.

Casandra: What's wrong with Belinda? I texted her and she sent back all tearful emoji's.
Carrie: She saw that Brenda posted about her new finery shoes and that Brenda got more likes than she did when she posted about her new sandals.
Cassandra: So she's drowning in the baby pool again? I should have known. Just for that I'm liking Brenda's shoes!!!
