1a.
Personal preference meets tradition/custom.
Literally: “I must go with what I’ve predetermined to be my
personal preference for specific situations/circumstances.”
For instance, to be used in reference to what your favorite
food item (typically) would be during any specific event or moment. A
better way of saying: “You KNOW I gotta go with the MALTballs right now.” Most accurately this is stoner slang; when you'
re in the convenience store, high with your homies, grab your favorite snack and say "Gotta have my
pops/popz/pawps/pawpz."
2a.
Casual reinforcement for one'
s personal preferences; passive self-assertion. It's a marriage between "What can I say?" "You know me," and "Nothing but the best for me"; "What can I say, nothing but the best for me"; similar but not equal to "That's how I roll." Often but not always expressed with palms up, shoulders shrugged.
