Someone who is chill and enjoys the open road, not very career or money-driven. Laid back, but a true seeker of individual freedom. Comes from the film "Easy Rider". Though not necessarily a drug-user or motorcyclist.
That Wyatt is an easy rider. He just gets on his motorcycle and goes, no strings attached. That's freedom, man.
Sexual position involving a girl, two guys, and simultaneous handjobs. The men are standing either side whilst the girl is kneeling and holding the mens penises like she is riding a chopper. Money shot optional. Smile mandatory!
A demonstration of the "easy rider" position can be seen in many adult movies and magazines, particularly near the end.
