nasturtiums 

Old yorkshire speak, part of a phrase.

If you cast nasturtiums upon someones character you perhaps imply that they have done something they shouldnt have done.

"I do hope you're not casting nasturtiums about my character young lady"

Sweet Nasturtium 

A sex act involving two (2) people making out with each other in such a way as to simultaneously give oral sex to a third party

We're going to start sloppily making out while moving toward you. And if your genitals just happen to get in the way and a Sweet Nasturtium happens, it's your fault!
