I have to go do something
A sad excuse to avoid a person you don't want to be around. It’s like saying you’re tired, but you’re actually just annoyed.
'I have to go do something.' He left me during the middle of a burger like I was a bad side order.
'I have to go do something.' She ran out of the bar like I was a broken drink.
'I have to go do something.' He ghosted me mid-conversation like I was a boring podcast.
