create alias cocksleeve_insertion (87) -> penetrable_sex_toy_insertion (166)
create alias cocksleeve_in_ass (22) -> penetrable_sex_toy_in_ass (101)
create alias cocksleeve_in_mouth (76) -> penetrable_sex_toy_in_mouth (143)
create alias cocksleeve_in_pussy (8) -> penetrable_sex_toy_in_pussy (14)
create implication penetrable_sex_toy_in_ass (101) -> penetrable_sex_toy_insertion (166)
create implication penetrable_sex_toy_in_mouth (143) -> penetrable_sex_toy_insertion (166)
create implication penetrable_sex_toy_in_pussy (14) -> penetrable_sex_toy_insertion (166)

Reason: Just came across these tags, and looks like the cocksleeve in cocksleeve_insertion are all penetrable_sex_toy, and also some penetrable_sex_toy_insertion implication.

Huh, weird that cock sleeve is invalidated rather than disambiguated. As discussed in topic #13728, it has several meanings, but it does convey useful information. I suspect cocksleeve_insertion exists because a user couldn't figure out the name of penetrable_sex_toy tag, and invalid_tag page was unhelpful.

All of this is to say, cocksleeve_(disambiguation) might be a better target for alias.
