“Pärchenallergie” playfully captures the post-break-up blues of someone who now reacts to every lovey-dovey couple as if they were a rash-inducing allergen: public kisses make her queasy, pet names like “Hase” or “Bärchen” trigger eye-rolling, and all that shared dopamine feels downright toxic. Annett Louisan wraps this grumpy yet humorous rant in a sweet chanson style, turning heartbreak into witty self-irony: she’s not against love itself, she’s simply “intolerant” to its public display while still nursing old wounds. The song invites listeners to laugh at the exaggerated metaphor—comparing romance to nuts or celery some people can’t stomach—while secretly empathizing with that relatable urge to flee when everyone else seems blissfully paired up.
