Hi everyone

Really hoping you can help me. Ok so everyone knows S.W.A.L.K means 'Sealed with a loving kiss' but I've been given a pic of my Grandma and she wrote a lovely message to my Grandad on the back with the following acronym on it.
I really want to find out what it means as my Dad never knew his Mum as she was killed when he was 3 and now I've finally managed to get him a pic of her, I'd love to be able to tell him what it is so he has some insight into her and my Grandad's relationship. This is it:

R.A.S.L.Y
B.O.L.T.O.P

Can you help please?
