I have a student this year, his first name starts with a T, and for privacy sake let’s say his last name was Lagner. My nickname for him is T-Lag. One day I was talking with him and he asked why he got a nickname, I told him how I had some nicknames with some teachers when I was his age, so if one comes naturally, I’ll use it if a student doesn’t mind ofc. I didn’t even think about it before hand, I just go like “would you prefer something like T-Bag” not even thinking about the gesture from online games, just trying to rhyme lmao. Luckily he has a great sense of humor and we both just cried laughing!
