When you befriend someone to get them to sign up for a 3 yr contract for the new iPhone and blaze you up fat, but ghost you when the Bill's pile up at your house and the creditors are calling 24/7

Jeffing

Spamming small groups of friends via text or social media groups with annoying news headlines from unreliable sources. Following up with strong calls to take actions. Slinging mud and engaging in personal attacks when asked to cease and desist.

Quit jeffing me already! You've that stupid YouTube video link 100 times already and nobody cares. You're not going to save the world by posting spam to your friends followed by insults.
