Certain brands of shampoo, cigarettes, home made curry while it's cooking, Thatcher's Katy Cider, hashish being smoked out of a pipe with no tobacco in there, the smell of a new vinyl, the smell of a new video game (seriously, open a new case and get a whiff of the manual, there's certain games that have a manual that's made out of a more texturally rough sort of paper, feels more like thin, thin card than paper, and it smells incredible, metroid prime always reminds me of this,) clothing that smells of a loved one, freshly mowed grass..
