Yes, I know what the term means, but for some reason I find the word itself funny. Maybe it's the combination of silly sound, dirty meaning, and the tendency of anyone I've heard say it turn it into an onomatopoeia (one of those words that sounds like the thing it's describing). Everyone, say it with me:
"BUKAKKE!"
(If you don't know what the term means, ask me. Googling it would probably take you to some porn site.)
