Bump and Grind of Chicken

An addendum to my earlier frenetic ponderings about the origin of the band name "Bump of Chicken" - they were in junior high, right? Tell me right now, without thinking about it, in the first 50 words you learned in your foreign language class, how many of them had violent or sexual connotations?

...that's what I thought. Within my first two weeks of Japanese, I knew how to say "pedophile," "to blow up/cause to explode," and "set my loins on fire." Valuable knowledge, that (which has since been forcibly evicted from the recesses of my memory, against my will).

In any case, does it not make sense that one of the few action verbs they knew to replace "attack" was...bump?

Well, at least a little more sense. In theory.

It still has my vote for most ridiculous band name.
