Sloths are literally too lazy to go looking for a mate, so a female sloth will often sit in a tree and scream until a male hears her and decides to mate with her

Brb trying this

So... Bumble then.

My (sloth) dudes, if the chick you want to hook up with just sits there screaming, I would consider that a major red flag.

Partially true. Though female sloths will release a mating call, it looks like a female in estrus will be about 200% more active than normal.
