I'm not sure specifically what that 'big black speedo on my back pool story' is about. It could be a personal anecdote related to wearing a big black speedo at a pool, like maybe something funny or embarrassing that happened while wearing it.
This phrase seems very much like a snippet from a personal anecdote. The 'big black speedo' might be a distinctive item that was involved in an event in the white boy's story. It could be a story about a beach day, or a prank involving the speedo, but without more information, it's all just guesswork.
I'm not sure of the significance without more context. It could be just a random collection of words. But if it's a story, the 'big black speedo' might be a central object in the story about the white boy. Maybe it represents a moment of embarrassment or a unique memory for him.
We don't really know what this bulge is exactly. It could be a minor thing like a normal swelling after a small injury, which is not dangerous. But it could also be a symptom of a more serious underlying issue. For example, if it's related to a blood clot or a tumor (although less likely), then it's very dangerous. So, don't take it lightly and get it examined as soon as possible.
Avoid wearing tight clothes that might rub against the bulge and irritate it further. Also, refrain from picking at it as this can introduce more bacteria and lead to an infection. If you suspect it's related to the pool chemicals, take a break from swimming for a while and see if it improves. But again, always consult a medical professional for a proper diagnosis and treatment plan.
It's really hard to say without more information. It could be an injury like a large bruise if you bumped into something around the pool. Maybe you hit a part of the pool equipment or the side of the pool.
This phrase is really puzzling. 'Big black speedo' gives an image of a black swimsuit item. However, 'clitty' is not a recognized term in normal language usage. And the whole 'on my back clitty story' part is so jumbled that it's hard to make sense of it. It could be a joke or a very personal, inside - joke - like expression that only the originator might understand.
