A Riggot is somebody's Anus. I have no idea where it came from, it's just a term use most frequently in the Northern half of England, Mainly Manchester.
Mick: "Dude...Did you see how fit that lass was?"
Jonny: "Omfg Yes...I'd love to lick her Riggot"
a hot chick (rig) that is recently discovered but does not belong to the so called 'popular' group. it refers to hot/fit chicks with a good body that float with the wrong crowd, that just dont match the rest of their group because they are a rigoon.
tom: oi mate, how hot is that chick sitting over there
ben: yeah mate shes so fit. but ive never seen before, does she hang out with the sluts and popular girls?
It's what Italian trash try and pass off as ricotta. You know, the cheese? The one that real Italians pronounce using every vowel and consonant sound in the actual word.
"I like dis rigot in this manigot. My grandmudda's straight off the boat AND IF SHE KNEW HOW I SPOKE ITALIAN SHE'D GUT ME IN AN INSTANT."
