Top Suds

Top Suds is when someone orders a beer and offers the first sip to a good friend. It is impolite and near insulting to refuse top suds when offered. Top Suds can also be used with any other dibs-style act such as fresh clothing, snacks, and uber seat picking. Asking for Top Suds is not the same as offering, you can refuse to give Top Suds and it won't be disrespectful.

Friend 1: You want Top Suds on this oven roasted pizza?
Friend 2: You're offering Top Slice Suds?! Thanks man!
Friend 1: Top Suds!
Friend 2: Top Suds!

Friend 1: Hey I'll take the IPA
Friend 2: Oh dude can I try that?
Friend 1: You're asking for Top Suds? Yeah that's fine.
