Iron Man's nickname for Thor stems from one of the most recognizable action flicks of the 1990s: "Point Break." Directed by Kathryn Bigelow, the 1991 film follows undercover FBI agent Johnny Utah (Keanu Reeves) as he infiltrates a crew of surfers who've become notorious for their bank robberies — dubbed the Ex-Presidents for their decision to wear masks of former United States Presidents while doing so. Their leader, Bodhi (Patrick Swayze), dons a scruffy beard and has grown out his blonde hair, making him a close visual match to Thor himself. The nickname would return in "Thor: Ragnarok," too, as Thor attempts to unlock the controls to the Avengers' Quinjet.
All in all, Tony Stark's "Point Break" nickname is far from the most inspired one he could've given Thor, and it's far from the only moniker he's dished out during his time in the MCU. Thanks to YouTuber SuperDuo, fans can look back on all of Iron Man's nicknames for his friends as well as his enemies. Among the most notable are him calling Hawkeye "Legolas" — the bow-wielding Elf played by Orlando Bloom in the "Lord of the Rings" and "Hobbit" trilogies — and referring to Ebony Maw (Tom Vaughan-Lawlor) as "Squidward" for his resemblance to Rodger Bumpass' "SpongeBob SquarePants" character.
"Avengers: Endgame" even saw Stark give Thor a second nickname, "Lebowski." Due to his lazy nature and unkempt look, he wasn't too far off from Jeffrey "The Dude" Lebowski (Jeff Bridges) from 1998's "The Big Lebowski." One has to imagine that if Iron Man somehow returns to the MCU down the road, he'll bring plenty of new nicknames with him.
