Ninja disgust

When someone, usually your parents, randomly springs a topic, usually sex related, onto you unsuspectingly. Much like a ninja attack its always a surprise and sometimes its deadly.

"Son...I found these condoms"
"Woh! Ninja Disgust...how about some warning next time"

Example 2: I got ninja dick. that shit maybe 1 or 2 inches long till I get a hard on but then that shit massive.

ninja Jacky

When the world sleeps the stern worm makes his move, generally in the dark of night. He attacks with precision and skill, no boner stands a chance, often beats his victim dry, until it pukes. Causing Indian burn. Usually attacks to anime.

Ninja Jacky struck mid night! Consider the meat beat!
