U.S. Olympic volleyball badass Destinee Hooker knows people are amused by her name ... she knows some people laugh ... but she doesn't care ... she believes it's a "blessing."
Hooker -- who's CRUSHING it in London right now (indoor team is undefeated!) -- tells TMZ, "When it comes to my name, I honestly find nothing wrong with it. I love my name."
Still, Destinee admits she's not deaf to the jokes ... "I have been dealing with it since I was a child. People can be childish."
There was almost no Destinee Hooker at all ... the 24-year-old tells us she nearly died at birth, and when she survived, her father was inspired to give her the name "Destinee."
"Since I was a blessing, [my father] spelled it uniquely. So I am thankful to be here and glad my Dad gave me the name."
Destinee adds, "No reporters have asked me about my name. You are the first :) thank you for asking by the way."
