Fill with bliss; filled with or experiencing bliss.
2008, Robin Wasserman, Skinned:
As far as I was concerned, bliss mods were bad enough when I was on them too, always leaving a weird moody aftertaste, like crashing after a sugar high. Staying cold sober while the rest of them blissed up?
2011, Marge McFarlane, Revelations:
I pushed the thought of my mom out of my mind and reflected on my first sexual contact with George. Oh my God, I just couldn't relive it enough. I was totally blissed up.
