What does S.A.S.E mean?

Question

so i'm trying to get micheal phelps autograph and it says to send a self addresed stamped envelope. does this mean that you need send one envelope in the other i'm confused

Answer 1

Inside the envelope you're sending, address an empty envelope to yourself and put a stamp on it so they can send it back to you.

Answer 2

Yes, you will send another envelope inside the one you are sending. On the envelope you include inside put your name and address on it (in the To: area, not the From: area) and a stamp so it can be sent back to you.

And, S.A.S.E. means:

S-elf

A-ddressed

S-tamped

E-nvelope

Answer 3

send a nude picture inside
