2nd Definition: A disease which alters the mind into finding men over the age of 38 attractive.

Commonly found in young adults, DILFism affects one's perception of a "hot person". To classify someone as a DILF, they must meet the three requirements of a) having children, b) being over the age of 38, and/or c) having played OR been a father.

Symptoms of DILFism include:
- "simping" or feeling a sensation of ovulation when presented with an attractive older man
- strong romantic and/or sexual feelings towards men that a) have children, b) are over the age of 38, or c) have played a dad in a movie, TV show, Grammarly commercial, etc.
- finding geriatric or men over the age of 38 attractive
- creating a worshipping site for a man classified as a "DILF"
- and much, much, MUCH more
