The act of instantly killing a conversation due to the hideous timing and inappropriate delivery of awful jokes.
Example 1:
Watching paranormal activity in suspense

Steph: "nom nom"
*SILENCE*
Person A: "good one"
Person B: Stop doing a Steph!

Example 2:
When attending a buffet

Person B: "Its £15 per head"
Steph: "What happens if you take more than a head?"
*SILENCE*

Example 3:
Listening to Beyonces song 'Irreplaceable'

Everyone: "To the left, to the left..."
Steph: "What happens if you wanna go to the right?"
*SILENCE*
