23a - LUNARORBIT (Revolution around the moon)
31a - CAREFREELIFESTYLE (Existence like Riley's)
41a - SUPERBAZOOKA (M20 rocket launcher)
62a - BIGREDMACHINE (1970s Cincinnati team nickname)
73a - TRIDENTSHAPED (Like the Greek letter psi)
93a - EXTRASPECIAL (Like a real treat)
101a-MITSUBISHIECLIPSE (1990-2011 sport compact car)
So apparently the theme involves compiling a list of brands of chewing gum, all presumably made by Wrigley, and combining them with other words to form longer recognizable phrases to go in the grid. I couldn't resist doing a little googling to see if the list comprises the entire Wrigley field and it does not - Juicy Fruit, Doublemint and Freedent are notable omissions - but it's still a pretty impressive accomplishment to get seven of them into a puzzle in more or less common phrases.
Okay, I just discovered that Bazooka Bubble Gum is not a Wrigley brand so maybe that shouldn't count as a theme answer - I'm not going to EXPEL (88d - Kick out) it though because it led me to discover this:
One feature I noticed that may or may not have been intentional is the Tennis shot (79a -LOB) crossing the BBSHOT (57d - Air rifle ammo) in the grid and right next door is RYDER (80a - U-Haul rival), the famous maker of air rifles. Stuff like that tickles me.
Not much else to say about the non-theme fill today - it didn't exactly IRIDESCE (89a - Shimmer with rainbowlike colors) for me, but it certainly satisfied my SWEETTOOTH (15d - What candy satisfies) and that's enough to make it a winner in my book. I'll leave you with a little Salsa to counter all that sugar - you'll have to find the inspiration for it in the grid yourself:
