| I know one and he goes by "Seb." |
| Bash |
| I love this name. In another life I will have three boys: Sebastian, Augustus, and Theodore. |
Same. |
| I only like Bash |
| I LOVE it but last name is very long and ends with the same letters, so I thought I could get away with it if we used the nickname. But i really like how the whole name sounds. |
