You're as cuddly as a cactus.
You really are a heel
Your soul is an appalling dump heap
Given the choice between the two of you, I'd take the seasick crocodile.
You're a three decker sauerkraut and a toadstool sandwich with arsenic sauce!
You're a nasty wasty skunk
I wouldn't touch you with a thirty-nine-and-a-half foot pole.
You have all the tender sweetness of a seasick crocodile
You're as charming as an eel.
