A br0tal effect on yourself where you turn to drink, flatcaps, homosexual songs & dancing like a tard.
Another part of the effect is sitting up the back seat in the cinema and having nothing but banter & taking the pish out of the movie your watching.

I had the jensen effect last night, i woke with a hangover and im still laughing at Ginger Goats.

The Erin Jenson

When a person with a theoretically high level of education posts conspiracy-driven or otherwise non-factually derived content and wholeheartedly believes they're in the right, despite a base level of critical thought showing otherwise. Commonly followed by doubling down, then claiming oppression after the predictable mass outrage.

Wow, they totally did the Erin Jenson with that post; I thought a child with a base level of critical ability would've been able to see why it was wrong, but they really went for it. Didn't even know this could happen at elite colleges.
