look up any word, like usuratonkachi:
(v) The shattering of a pane of frozen semen, generally upon the body of a lover/companion. The semen is generally frozen three to four hours prior to the act itself, as a thin layer of ejaculate is spread across a mirror/glass surface and placed within a domestic freezer. The moment of impact as the pane of semen breaks is understood to provide an endorphin rush in both partners.

The practice began as a niche gay fetish within the upper-class theatre community of Ireland in early 2012, from which Sugarglass Theatre Company takes its name.
"I had a wonderful time last night; we sugarglassed 'till the break of dawn"

"This play is awful, let's go home and sugarglass. The pane should be frozen solid by now"
