Giles and Sepentine's definitions
The Mustard Jumper is when you are going down on a lady and she has a whole rug going on downstairs. In the process of pleasuring the lady a bit of that rug tickles your nose forcing you to sneeze! (Like when you smell a pungent mustard). In the process of sneezing you pleasure her more forcing her to jump in pleasure.
Jeeesus, Giles was going down on Serpentine the other night and he gave her a mustard jumper. She nearly hit the ceiling apparently.
