A Flemish Sea Captain occurs while one partner is performing oral sex and blows their nose (ideally with a large amount of phlegm) onto their partner's genitals.
Suzy: "Oh yeah...oh yeah..."
Jonny: "I'm so stuffed up with all this phlegm...I can feel it dripping down my nose."
Suzy: "It's okay, just give me the Flemish Sea Captain"
* (sound of blowing nose)
Jonny: "Crap, I've got a nosebleed..."

When one partner is performing oral sex on their knees with the recipient in a standing position. The 'performer' then closes one hand in a thumbs-up position and inserts the full length of the thumb into the partner's rectum. Giving the in-and-out motion reminiscent of a hitch-hiker.
