Although technically not an actual usage of the ability, she engages in similar behavior earlier when first meeting Blue by grabbing him suggestively and either meowing like a cat (Manga) or otherwise licking him (anime) largely due to becoming infatuated by his handsome appearance, only for Blue to reject her in horror and disgust, causing Bulma and Krillin to deduce his homosexual leanings.
Bulma shakes her butt at General Blue in an attempt to seduce him, but it does not work on him and he is then implied to be homosexual.
