When acting as a bench press spotter for a male partner, Glifting involves dangling ones testicles into the mouth of the lifter on the press. Similar to 'teabagging' but specific to male bodybuilders - derivation is believed to come from a combination of 'Gay' and 'Lifting'.
'Nice curls you were doing there, Jeff - fancy a spot of glifting? Don't mind if I do, Roger - I hope you've shaved your balls this time!'
