A love child born out of a tinder match.
Tindren is/are a child or children which was the outcome of a tinder match and subsequent hook-up.

On-looker: 'Oh that child is adorable!'
Mother: 'Don't be looking at my tindren Bitch!'
On-looker: 'Tindren!? Be gone Woman!!'

Most likely scenario: "Hitched after a frequent tinder match the, now married, couple sleep in separate beds after a the first year’s anniversary of mutual resentment. Contact is kept to a minimum, forcing guilt upon their tindren as ‘the reason we didn’t divorce’.”
