To become highly intoxicated from alcoholic beverages, in such a state that the host can not stand nor speak. Derived/Inspired ny the character 'Stepehen James' who becomes 'Stiggied' at every available opurtunity.
Fuckin' hell, look at him, he can't evenb walk!! He's fuckin' stiggied!!
Not to be confused with Biggie Smalls. When it's butt nasty, hot, sticky and dank outside. Humid oven like weather that makes you're skin suffocate and your balls smiggy especially when wearing underwear.
I have to have an extra dedicated stick of deodorant for smiggie balls weather like this.
