look up any word, like dirty sanchez:
A very rare parasite that is hard to find until it is latched onto your arm and WON'T COME OFF. The only way to get rid of Flynn is to ignore it, and it might go away, but it might also stay and try harder to get your attention. Sometimes it is possible to tame a Flynn into doing whatever you damn well please, but that is also very unlikely.

Ways to spot a Flynn:
You'll often find him following you at a distance. If you make eye contact, it will take this as an invitation to come up and start yapping your ear off.
The Flynn is also a creature that will copy its host, so if you start wearing certain clothing, say very bright pink leg warmers, you will probably find the Flynn covered with bright pink spots. Also, if you say something that gets any kind of positive acknowledgement then The Flynn will continuously repeat said phrase.

Expanding the anus using two middle fingers and for extra kicks inserting a tounge into the rectum or other objects if you are a daring individual.

The act of inserting two middle fingers (with the knuckles facing) into someone's anus. The act can be self applied but is not as cool and could result in carpal tunnel sydrome and anal bleeding.
Holy shit, you just got double flynned. At least you didn't get a four bagger.
