[請益] grind up 在文中的意思

[norge (Boston)]

在一篇關於德國巴伐利亞服裝的文章中

On a recent night, the dance floor of Neuraum was a festival
of dirndl in its endless varieties. There was a black goth
dirndl cascading over tattooed calves. Next to it, a gaggle of
pink and baby blue ones worn with sneakers. Young men sweating
in woolly calf warmers and felt hats were grinding up to young
women in flowery aprons.

倒數第二行中，grinding up 在文中的意思，要怎麼理解比較好呢？

另外

Plus, for many, he said, "wearing a traditional outfit is a license
to get completely hammered whilst still feeling virtuous."

第二行中的 hammered 是什麼意思呢？


謝謝!
