refer to people as 'kid' when you talk to them. this works especially well if they are older or more senior than you. here are some hand picked examples:

"did you get my email kid ?"
"can i take next week off as leave please kid"
"your false teeth have just fallen out kid"
"no kidding, pick up your kid's kid kid "

(this last one is ideal if you are trying to convince your friend that you actually do want them to carry your daughter's young goat).
