When two or more people are in a shower and the male begins to perform the "helicopter dick" while standing under the shower head, resulting in the flinging of water into their partner(s) mouth(s).
"Ugh, I didn't want to re-straighten my hair today but my boyfriend kept flinging his wiener water on me and its starting to curl."
