To eat out a girl when adorning a full beard whilst she is on her period, thus turning your beard red and therefore turning you into a viking.
The girl I'm seeing told me she was on the rag when I went to eat her out, I told her to let me get my Leif Eriksson.

When someone comes over to fix things but breaks more things and the original thing is still not fixed. Most of the time this is followed by vacation leave.

A man who does calisthenics. He has a legendary bloodline. His grandfather was an infamous climber who would climb the holy lands of your mother’s pussy. His father created National Geographic and is a skilled archeologist. His brother Oliver packs a huge 1000$ telescope for which he shows off to his girlfriend Jacqueline. Leif went to a tennis camp in Wake Forest North Carolina where he learned how to jerk off to the tennis balls. He thinks he is the main character, but that role is reserved for James Chen. Whenever Leif fucks a girl he says he will give her the one piece. Leif’s penis curves like an L. You may think that is a problem, but whenever he gets a boner, his penis becomes so long that it doesn’t even matter because he will rail you sideways.
Omg this guy’s penis was so weirdly shaped but so long. He kept telling me that the one piece was real and that he would give it to him. What even is a one piece? Sounds like you have a Leif Sloan.
