The bulk update request #12969 is pending approval.
create implication feminization (2600) -> gender_play (119)
create implication masculinization (187) -> gender_play (119)
create implication forced_masculinization (33) -> masculinization (187)
create implication forced_masculinization (33) -> forced (114497)
Reason: These seem logical to me. bimbofication and himbofication could also be included, but I'm not sure if exaggerating one's current gender should be considered gender play. (gender_play previously had no wiki definition; I just made one, but am open to suggestions if you believe it is inaccurate.)
Also includes implications for forced_masculinization that mirror those for forced_feminization, while we're at it.
