Cheap perfume that smells terrible and makes everyone except the perfume wearer sick. Usually worn by women who are 50 years of age or older. Tends to stick to hair and clothing.
"Susan stopped by last night and my whole house reeks like old lady perfume. She hugged me and I had to take a shower and wash my clothes to get it off me."
Greg: "It stinks in here, what is that?!"
Marsha: "Alice was just here and I'm pretty sure she bathed in old lady perfume this morning."
Greg: "Gross. Go take a shower."
