 Get the half and halfmug.
Get the half and halfmug. In an Irish bar, a drink that's half Guinness and half lager.  Not called a "black and tan" since those colors commemorate the british military force used to supress Irish uprisings.
In an English pub I'll order a black and tan, but in an Irish establishment, I'll order a half and half.

 Get the half-and-halfmug.
Get the half-and-halfmug. A drug cocktail containing one half a 30mg Adderall and one half a 10mg Valium. The effect is a balance of the best aspects of cocaine and ecstasy. A counter-intuitive mix as the pharmaceuticals work at cross purposes, but the synergy induces a euphoric energy which is free from anxiety. Impaired memory is a side effect of the Valium, which can be another benefit, depending on what you did whilst under the influence of the cocktail.
"Big night planned at Rose."
"I'm definitely in, and tonight I'm rolling with a half and half. No way my sinuses can survive another coke binge."
