snail helmet

When you place your balls on top of your penis and said structure resembles a snail. Then said structure is placed gently upon your bae's forehead.

Yo Whitney, you know I'm putting this snail helmet on your head after you lost the bet.

Mary Helena

She's the type of girl who is shy but put her with the right people and she's the happiest and most bubbly person ever. She is very supportive and loyal and be with you through thick and thin. Mary Helena tries to be friends with everyone she meets and does whatever she can to make everyone happy. In a relationship she seems innocent and sweet but she's kinky as fuck. If you find a Mary Helena, keep her. Hold on to her forever. You'll never find another girl like her.

Person 1: Who's the beautiful goofball over there?
Person 2: That's Mary Helena.

Tooth Helmet

Initially coined to describe an extremely strong artificial shell or crown created to protect and reinforce very weakened teeth. In 2021, the strength of this shell was estimated to be approximately 4 times stronger than natural teeth at TLC dentists in Richmond Australia by the proponent dentist Dr Eugene Lee.

The phrase was subsequently mistranslated in several Asian countries and is now used to describe an unintended unaesthetic bowl style haircut with two middle parts at the front.

That guy is so fit but meh Tooth Helmet.

peruvian bike helmet

a sexual act in which one person excretes feces into their hands, then proceeds to smear it on their partner from the forehead, to the base of the neck. After this sand is then poured over the head of the receiving partner and is then followed by ejaculating over the sand, further cementing the gritty shit helmet onto the scalp.

Donald Trump was seen last Thursday sporting a Peruvian bike helmet, an admittedly much better trade up from his usual toupee.
