Out of Plane Sight
Explanation
Explain Bear
Listen up, buttercup. The joke plays on the phrase "plain sight," twisting it to "plane sight." A kamikaze uses a plane, see? The joke is a play on words, making a punny connection between the visibility of kamikazes and the fact that they are flying in a plane. I bet you are one of those people that unironically uses the word poggers.
