I got so many hickeys people'll think I'm a leper.

Our reading
An editorial interpretation.
The speaker exaggerates the visible effect of numerous hickeys by imagining people mistaking them for signs of disease. The comparison turns a private sexual aftermath into a worry about public appearance. Its bluntness supplies the humour without making the imagined diagnosis a factual claim.
