| Dull |
| A drag |
| Dullsville |
| Unpleasant |
| Bo-o-oring |
| Too Puritan |
| Too serious |
| A real drag |
| Quite a drag |
| That's bad, man |
| Gravely serious |
| Like a buzzkill |
| Party-pooperish |
| Like wet blankets |
| Far from pleasant |
| You're ___ at all! |
| Completely joyless |
| Like party poopers |
| Far from enjoyable |
| Like a wet blanket |
| Not at all exciting |
| Like a party pooper |
| Like a stick-in-the-mud |
| Like a wet blanket, so to speak |
