My friend texted me something really inappropriate but idk how it could be ?

So I was sleeping over at my friends house and was watching tv while she took a bath (lol) and she texted me saying, "Hi. I'm in the bath." and then 3 minutes later saying, "So wassup. How is the t.v. Show? Just having sex with my waterhose." That is exactly how it us written, caps and all. This is weird because she is the type of person who claims to have never cursed in their life and doesn't like saying the word "gay" (idk why). This isn't her usual texting pattern really but nobody else was home and she came running out a couple minutes after saying that she meant to type "So wassup. How is the t.v. Show? Just getting out of the bath." and that she wasn't really looking while she was typing. Her bath has this old fashioned detachable hose thing- maybe that is what she meant? Oh and also she usually would be really freake out/scandalized about this type of stuff but she didn't seem as freaked out as usual this time. She was just like "I don't even know what a waterhose is.". So my questions are... How could she have typed the first part right and not the second? Do you think she was doing something inappropriate with the water hose and got some kind of thrill of texting that and meant to delete it but ended up sending it instead? We are only 12 almost 13 and she is super conservative about that stuff-her parents aren't really at all.
