Neil Strauss, in his 2005 book The Game, describes Jeffries as the "godfather" of the modern pick-up artist community.

[4][5] He taught workshops and promoted a collection of neuro-linguistic programming (NLP)-based techniques called "speed seduction".

[4] His teachings claim to show men how to create the desired emotional state in a woman by leading her imagination for the purpose of seduction, rather than to focus on a specific behavior or action of hers, as the desired outcome.

[6] In 1992, he was on a segment of NBC's Faith Daniels Show, appearing with men's rights activist Mel Feit and feminist and ethicist Bruce Weinstein.

[9][10][11] In 2000, Jeffries sued John White (also known as Don Steele) alleging invasion of privacy, business interference, slander and libel.
