Softboiling 

When you dip the whole nuts into her pussy. No cock, just the nuts.

Me and my girl tried softboiling my nuts the other day. I'm still sore, but it was worth it.

softballing 

When you eat a girl out, you also use two fingers in the vag and one in the butt. As seen on 'Orange is the new Black' tv show

Nothing gets her off like a good softballing, it's like.. the trifecta of pussy whispering.

Soft boiling an egg ~ code for beating ones dick, or masturbating with ones penis.

I can't talk right now, soft boiling an egg. Talk later.

spitboiling 

Pursuing a fruitless and pointless endeavor.

Spitting in a pot to boil it would be a waste of time and energy and would likely never succeed, as well as being a frivolous and senseless activity which achieves no purpose in the first place, hence the term spitboiling.

"My mind is made up; you're just spitboiling trying to convince me."
"We haven't made any progress. We need to stop spitboiling and either change our approach or give up."
"Is there a reason you're doing that or are you spitboiling?"
