Awesome restaurant cafeteria chain in Texas that predominantly serves old folks, mailmen, and cops delicious, heart clogging, hot, homestyle food. Famous for people who push tea-carts full of iced tea, other refreshments, and condiments. (Unfortunately, the tea-carts have been done away with by new managment which SUCKS!)
I had the Luann platter at Luby's and let me tell you brother, it was off the charts!

a spunky girl who is unusually loud for her small size.
He ran around screaming like a Luby!

The feeling of too much lubricant after sex.
I felt so luby after last night's orgy. Silicone stays for days.
