An excerpt from the Scruf Handbook: Page 33, paragraph 4.
A slab of metal placed over the butt region to protect you from unwanted gaybee attacks. When the faggy attacker attempts to shove his fag stick in your butthole a loud "gong" sound can be heard as his dick crumbles against the steel. And now that fag is gonna get beatdown.
<gong!!!> "ohhh, your fuckin' dead now! My buttplate saved my browneye from gettin' gayified. YDB."
