Understanding Universal vs. Existential Quantifiers in Relationships

[bonfire09]

Any person who LOVES a SLOB is him(her)self a SLOB.

In this sentence does "any person who loves a slob.." involve a universal quantifier for the slob or a existential quantifier? I think its existential since it says "a slob"

Show how you are representing the sentence. What variable are you assigning a qualifier to?

I think the textbook answer to this sentence involves only a universal quantifier.
