1 definition by u7654erdsfgt

when someone promises you something and then doesn't do it, or when they say they will do something/hang with you/ speak to you, then just go and bum off another more interesting person

i.e selling you out.
student1: hang with me at break yeah?
student2: sure thing see you then

student1 catches student2 hanging with student3.

student2: sold out piece of shit.
