Eat the radish 

Eating the radish is when something fails to live up to expectations, as in how nice radishes are to look at, but how terrible they taste.

As in, "I hope I don't eat the radish today," or, "This pizza really ate the radish."

Eat the radish in the downstairs kitchen 

To orally pleasure the fairer sex's bulbus part of the nether region, with one's tongue.

Alright love fancy letting me eat the radish in the downstairs kitchen.
