Bobbing the Lolly is a term used by British Airways flight attendants meaning to give a blowjob. These are particularly appreciated by those long trans-Atlantic travelers, and is just one of the myriad services provided by these travel hostesses.
Sir Neville and Amanda had been necking for quite a while, when she piped up inquisitively and asked Nev if he'd like her to bob his lolly.

"Aye, I was crossing the pond at 10,000 meters and all the while one of those British birds was bobbing the lolly."
