What are your thoughts on them? I think they’re kind of cute…my favorites are CJ, RJ and TJ
As a nickname or a full name? I think these make really cute nicknames. They could easily be for a boy or a girl. 
A nickname, it’d be too short if it were a full name, and plus I think almost everyone assumes it’s short for something.
I like PJ DJ LJ TJ MJ SJ CJ EJ
I also like KP Pk lol x
I also know of a DJ who goes by that rather than his name but his initials are DJ and he is DJ in school too
All of them sound good except for BJ. BJ= blowjob and I wouldn’t want that to be my nickname especially when I’m in junior/high school. 
Avoid BJ at all costs.
DJ, RJ and TJ are cute though.
Yeah, BJ s not a good option.
I like CJ, JJ, GJ, EJ.
I love initial nicknames. I’m fond of AJ, EJ, IJ, KJ, LJ, PJ, RJ, and TJ.
In general, I’m not fond of them. I just think names are so wonderful on their own that I wouldn’t want to minimize two beautiful names to two little letters. It seems a shame to pick out such a gorgeous full name and then only use two letters from it! But I know others like it, and I guess it’s a fine choice. It is a choice, after all. I’m not opposed to EJ, JJ, KJ, and MJ, but I likely wouldn’t use them. [name_f]Every[/name_f] instance of names that would fit those syllable patterns that I can think of ([name_u]Everett[/name_u] [name_m]Joshua[/name_m], [name_m]Jack[/name_m] [name_m]Julian[/name_m], [name_m]Jack[/name_m] [name_m]Josiah[/name_m], [name_f]Julia[/name_f] [name_f]Josephine[/name_f], [name_f]Kaia[/name_f] [name_f]Josephine[/name_f], [name_m]Killian[/name_m] [name_m]Joseph[/name_m], [name_f]Maria[/name_f] [name_f]Josephine[/name_f], [name_f]Maria[/name_f] [name_f]Juliet[/name_f], [name_u]Micah[/name_u] [name_m]Jeremy[/name_m], etc.)–I don’t think I’d nn any of them EJ, KJ, JJ, or MJ. But I guess it’s like that for any nickname–I love [name_f]Arianne[/name_f] nn [name_u]Ari[/name_u], but I’m sure there are others out there who love [name_f]Arianne[/name_f] who would be sad to see it shortened at all. But yeah, if I had to pick one, it’d likely be EJ, JJ, or MJ for a boy, or KJ or MJ for a girl.
