this is a sexual youthanism made up by my friend jay but now everyone in town and school uses it.
He had an unripe banana for lunch so spat it out and drop-kicked it causing a suspicous white mess on his shoe. After trying to explain it, jay and eventually other use "drop-kick a banana" as referance to anything sexual involving both a penis and a foot.
Jay never ate a banana again
rhiannon drop-kicked her boyfrieds banana last night.
