Waikiki a neighbour in Hawaii well known for its surfing and paddling boarding... A Waikiki Cumshot is when a male engages in water sports... I.e urinating on their male or female counterpart in a sexual fashion.
My husband give me the most powerful Waikiki Cumshot last night, it was so warm and heavenly.
A person that knows it will fail at something, only to be waiting for it to happen again.
Person A: Oh god i think i'm gonna fail the test, i really want to know what the results are.
Person B: I don't. We have more tries to fail again.
Person B: You're not an optmist nor a pessimist...You're a waitimist!
