Greggs’ Vegan Sausage Roll: A Strange Sensation

Greggs sparked a viral frenzy with its vegan sausage roll launch in 2019.

This unusual strategy sparked debates and jokes online, boosting sales and brand awareness dramatically. The takeaway? Mystery and humour combined can create viral magic.

KFC UK’s Offbeat Twitter Banter

KFC’s UK Twitter account is famous for its witty, often strange online personality. Their bizarre, humorous tweets and playful jabs at competitors have built a devoted following. This weird and wonderful approach makes KFC stand out in a crowded fast-food market and keeps customers coming back for more — proving that a unique voice is vital for viral success.

IKEA UK’s “Where Life Happens” Campaign: Embracing Real-Life Chaos

IKEA UK took a refreshingly weird approach by showcasing messy, real homes rather than perfect, staged interiors.

This honest, slightly chaotic marketing broke the mould and boosted engagement and brand trust.

Why Weird Works in Viral Marketing

UK brands that dare to be different and embrace weirdness often cut through the noise in a crowded digital world. Strange, quirky campaigns spark conversations, increase shareability, and build emotional connections — turning simple marketing into viral sensations.
