So I saw this on Instagram and I love these types of things, I know MN have some great comments when a thread like this comes along!
Me and my friend have been thinking of new ones but she's a lot better at it than me!
Some she's thought of are,
Torch - nighty lighty
Sponge - squashie washie
Lube - slidey ridey
Sleeping pills - deepy sleepy
Pond - fakey lakey
Nappy - crappy trappy
Coffin - ready beddy
Blow Job - mucky sucky
She put one for viagra as starty party but I wrote back rocky cocky. Proud of that one!
