Probably the best couple on the planet, both definitely listen to the same love songs (Eslabon Armado) and dedicate songs to each other on their snapchat stories.

A permit or pass combined with an image which allows the person you give it too to masturbate. In order for the M card to be valid, one must send an image with a caption or any other indication that the image you sent is indeed, “ok to nut to”
I sent my gf an M card with a picture of Ben Swole on May 4th. Nonetheless the nut is strong with this one

A kind of fivesome such as you would have between three people of one sex and two of the other but only straight sex occurs.
When his two buddies found wives, Charlie was worried about becoming a fifth wheel. But the occasional M-some really made him feel better.

Definitely a weirdo, stays up late at night, always parties, loves chipotle, and guys ;) definitely a hottie, very protective, likes Mexican music, probably a southern girl who was a lifeguard at some point in her life, loves the sea, and turtles, probably in a sorority too.
Guy 1: yo who is that? She's hot!
Guy 2: I don't know but with an ass like that her name must be Ashleigh M!!
