No, certainly NOT in the sexual sense.
Though I’ve omitted one of the statements I thought I should have previously included.
Tinka (in a sad & melodramatic voice): “I think it’s a pity that I never had a nick name at all.”
What should I have done? Pointing out that her given name “Tinka” was or is already the nickname or shortened version of “Katinka”? What kind of nickname could you take from “Tinka”? “Tinky” maybe?
